20600: When try to create dummy participant : page must be reloaded

Tue, 07 Jul 2026 19:44:35 +0200

When try to create dummy participant, if you don't reload the page, no action is done when you clickthe 1st time
This happen with mandatory attribute.

20599: When questions have a relevance equation, mandatory questions are not enforced.

Thu, 09 Jul 2026 08:57:18 +0200

I am seeing issues in a survey, where I have mandatory questions, and I am able to move forward without answering them
The issue seems to happen when questions have a relevance equation... that seems to kill the enforcement of mandatory questions.
When the questions don't have relevance equations, the mandatory rule is enforced.

This happens on v6 and v7

20598: Token overwrite when opening multiple survey tokens in different tabs of the same browser

Thu, 09 Jul 2026 12:35:34 +0200

When a user opens two distinct token links for the same survey in two different tabs of the same browser session, LimeSurvey overwrites the active token session data with the most recently loaded one. If the user goes back to the first tab and tries to save or proceed, the response data gets cross-contaminated or associated with the second token.

20596: Panel-Integration parameter (Survey-URL-Parameter) missing after copy

Mon, 06 Jul 2026 15:03:52 +0200

When I copy a survey, the panel integration parameters are missing in the result.

When using export / import to "copy" a survey, the panel integration parameters are not missing.

20595: Printable Survey not showing "other", after importing via txt

Mon, 06 Jul 2026 12:03:24 +0200

After importing a Survey via txt the "export" -> "Printable Survey" view does not show any other fields.
A workaround for this is: After importing open every question containing an other field, then saving the question (without any changes).
It seems as if saving the questions changes some parameter in the background, which is necessary for the Printable survey view.

Also it seems that the issue:
only occurs on txt import
applies to all question that have a built in other field option
is unaffected by other position and custom text

20594: It is not possible to delete answer options/subquestions after upgrading to 7.0.4+260620

Mon, 06 Jul 2026 12:52:47 +0200

After upgrading to LimeSurvey 7.0.4+260620 via Comfort Update, answer options can be created but cannot be deleted. The issue appears to affect all question types with answer options and subquestions.

20593: Array filter on single choice don't work anymore

Thu, 02 Jul 2026 16:48:07 +0200

The array filter attribute and the array filter exclude attribute didn't work in 7.X

20589: Direct link to view single response no longer opens a dedicated page since v7 — only a modal/popup, breaking shareable links

Wed, 01 Jul 2026 15:24:01 +0200

## Expected Behavior

In previous LimeSurvey versions (pre-v7), clicking view/edit on a response opened a dedicated page with its own unique URL, e.g.:

https://umfrage.example.tld/responses/view?surveyId=532561&id=280

This URL was directly shareable, colleagues or reviewers could be sent a link straight to a specific response without needing to log in, navigate to the survey, and manually search for the response ID.

## Problem

* Old-style direct links (responses/view?surveyId=X&id=Y) still resolve to a working page (confirmed on our instance), but this is no longer reachable from the UI itself.
* The response list now only supports a popup for viewing/editing individual responses, and popups cannot be bookmarked, linked, or shared via URL.
* This breaks existing workflows for teams that share direct links to specific responses (e.g. for QA, moderation, or cross-referencing with partners).

## Suggested Fix

Restore the option to open a response in its own dedicated page (either as default behavior or as a user-selectable alternative to the popup), so the URL updates to reflect the currently viewed response and can be copied/shared.

Alternatively: make the popup update the browser URL (e.g. via history.pushState) so the current response state is reflected in a shareable link, similar to how many modern SPA implementations preserve deep-linkability even inside modals.

20588: Error while import participants for csv file

Wed, 01 Jul 2026 10:28:10 +0200

Error while import participants for csv file

Invalid access codes skipped when the token field is filled in

for example:

tid,firstname,lastname,email,emailstatus,token,language,validfrom,validuntil,invited,reminded,remindercount,completed,usesleft
"1","first","last","first.last@gmail.com","OK","DIOnqyPDjZJPDws","pl","","","N","N","0","N","1"

When the token field is empty import executes successfully.

20587: Error participant token while editing

Mon, 06 Jul 2026 13:58:54 +0200

Error participant token while editing
Empty token value after editing survey participant

20586: Unabole to use installer GUI whith nginx or IIS

Tue, 30 Jun 2026 17:01:06 +0200

When trying to install a v7 version with a not configured nginx for url rewriting, redirection is /index.php/installer goes to a 404

20585: New editor throws error - 404 could not resolve request editor

Wed, 01 Jul 2026 15:20:13 +0200

In a fresh install of limesurvey 7.0.5 I can create and edit a survey with the classic editor. As soon as I switch to the new editor I can neither edit an existing survey nor create a new one.

To be more specific, when i try to create a new survey a survey is created but the redirect to the edit view of this new survey instantly throws an error.

20582: Several deprecation errors when using version 7.0.5 with PHP 8.4

Mon, 29 Jun 2026 16:27:08 +0200

I had to modify several files in order to get rid of a deprecation message:

20581: application/controllers/ResponsesController.php crashes (due to php 8.4)

Mon, 29 Jun 2026 16:48:43 +0200

The display of responses generates a php error:
ResponsesController::actionDeleteAttachments(): Implicitly marking parameter $responseId as nullable is deprecated, the explicit nullable type must be used instead
/srv/www/formulaire.unige.ch/html_root/outils/limeemploi/application/controllers/ResponsesController.php(808)

I've patched it adding a "?" before the second "int" on line 808:

diff ResponsesController.php.00 ResponsesController.php
808c808

< public function actionDeleteAttachments(int $surveyId, int $responseId = null): void
---
> public function actionDeleteAttachments(int $surveyId, ?int $responseId = null): void

I've checked, the error is still in v 6.17.10

20580: "Bootstrap buttons” layout does not display the input field when the built-in “Other” option is selected

Wed, 08 Jul 2026 11:29:58 +0200

In LimeSurvey 7.0.5, a multiple-choice question configured with the “Bootstrap buttons” question theme does not display the text input associated with the built-in “Other” option.
The “Other” button can be selected, but no text field becomes visible, so the participant cannot enter an additional answer.

Inspection of the generated HTML shows that the text input is present:

Other:
class="form-control input-sm bootstrap-other-input"
type="text"
name="Q16564_Cother"
id="answerQ16564other"
value=""
aria-labelledby="label--other"
data-name="Q16564other">

A hidden field is also generated:

type="hidden"
name="javaQ16564_Cother"
id="javaQ16564_Cother"
value=""
class="button-checkbox-other-value"
data-name="Q16564_Cother">

The visible text input therefore exists in the DOM, but its containing element remains hidden after the “Other” button is selected.

20579: Statistics can't be exported

Wed, 08 Jul 2026 14:21:45 +0200

When trying to export a surveys statistics, while having the output option 'Show text responses inline: on', 'View summary of all available fields: on' and 'Show graphs: on' selected, the statistics can't be esported as an excel file.
The file will be created but it will show an error in the actual file and no data. Furthermore, when using HTML for the output, the answers to the text responses won't be displayed.

20578: Survey activation fails when a survey contains a Ranking question due to a consistency check error indicating missing answer opt

Tue, 30 Jun 2026 12:09:37 +0200

Activating a survey containing a Ranking question triggers a consistency check error stating that the question has missing answer options, preventing the survey from being activated.

20576: Partial Scoring for Multiple Choice Questions

Fri, 26 Jun 2026 09:35:03 +0200

Currently, LimeSurvey calculates the score for Multiple Choice questions by summing the assessment values of all selected answer options. As a result, it is not possible to implement a scoring model that is commonly used in knowledge and competency tests.

In many tests, only correctly selected answers should contribute to the score, while incorrectly selected answers should neither receive points nor cause a penalty.

This behavior cannot currently be achieved using the standard Assessment feature.

If incorrect answers are assigned an assessment value of 0, participants can simply select all answer options and still receive the maximum score. Assigning negative values to incorrect answers introduces a penalty-based scoring system, which is not appropriate for many assessment scenarios.

20574: Unable to update with not compatible theme

Thu, 09 Jul 2026 01:08:59 +0200

This DB didn't update

Surely default theme ? Or Global default theme ?

20573: Database : ranking question contains unrelated information

Mon, 29 Jun 2026 17:21:21 +0200

In 7.X database contains the question ID and subquestion ID

But data are related to other subquestion ID

20572: Can not add new element to ranking question in 7.0

Tue, 30 Jun 2026 10:58:03 +0200

In 6.0 : we can add element in ranking quetsion after activation, not tru in 7.0

20571: Usage of max_subquestions rankking feature broken

Mon, 29 Jun 2026 17:06:42 +0200

We have max_subquestions where we can put a max column number for ranking question.
In 7.0 this setting is not respected.

20570: When not unchecking the "unseen or not answered" checkbox but editing a data set the screen freezes on save

Mon, 29 Jun 2026 16:45:25 +0200

Sometimes you need to adjust existing answers to add further details. When doing so at a lengthy survey, you sometimes forget to uncheck the "unseen or not answered" checkbox. In this case, the screen simply freezes on save and all edits get lost.

20569: Invalid quartile for crypted data

Fri, 19 Jun 2026 17:48:52 +0200

If data is crypted : quartile of numeric question are false

20568: Implicit conversion from float 0.5 to int loses precision

Thu, 18 Jun 2026 17:43:02 +0200

With crypted attribute , when try to get quartile, we cast as float, not if not crypted.

1. No reason of cast if we do not cast when not crypted (must cast as both)
2. Throw an error with debug set
