it's probably just a problem of specifity:

Must have been a browser or session cache issue. It's working fine now. Thx, please close the issue.

Well.. looks like it's solved in 3.0.3.

I wasn't aware before of the impact of debug setting in config.php - in my test environment this is set to 1, so asset manager is turned off..... that will explain why template changes weren't visible right away. Pffff.....

I added this to the doc yesterday:
https://manual.limesurvey.org/New_Template_System_in_LS3.x#FAQ_about_theme_customization

I'm using Version 3.1.1+180130, and I'm still having problems with the Asset manager. I create an extension of the bootswatch theme. Using the Theme Editor, I made some changes to "custom.css" and clicked on the "Copy to local template and save changes".

According to the theme editor, it saved it under: upload/themes/survey/extends_bootswatch2/css/custom.css.

When I launched my survey and viewed the HTML source, it claimed the custom.css file was located at: tmp/assets/5a4dff2b/css/custom.css. However, there was no file at this location when I checked it.

I suspect that the asset manager is dropping custom.css in the wrong location. I've consulted the document above about theme customisation, but it hasn't helped.

tbednall: can you please upload here your custom survey theme ?

Here it is. I found a workaround by uploading thie "custom.css" file to the location of the URL specified in the source HTML code (there was no file there). However, it would be nice to use the theme editor to make changes to custom.css directly.

/**
User custom CSS

In this file you can add your own custom CSS
It will be loaded last, so you can override any other property.
Also, it will never be updated. So if you inheritate a core template and just add here some CSS, you'll still benefit of all the updates
Does it update?

[data-number='1'] {
text-align: left;
}

#outerframeContainer {
max-width: 1080px
}

.hidden-question {
display: none;
}

I have the same problem:

custom.css entries of extended template does not have any influence. The assets folder "81ea70ff" found in the sourcecode of the survey does not have any file inside.

Version 3.3.0 released
