You have external plugin activated ?

I just check with webserver and AuthLDAP : no way to reproduce.

AuthLDAP is not activated.
Do I need to activate it?

I want to clarify this problem.
This issue only occurs to users with no admin privileges.
These users have permission to create surveys only. And I checked them at the use internal database authentication.
In the Plugin manager I activated all plugins excluding AuthLDAP.

I mean : did you have a ny plugin activated.

No need to activate AuthLDAP (or anything else)

Since the issue seems reatled to plugin : i think you can have an Auth plugin :)

can you check with debug mode activated ?
manual.limesurvey.org/Debug_mode

Checked wit an user without rights , but have roles …

No way to reproduce … :((((

I found what is the plugin that is causing this error. This is AuditLog.
I turned it off. And that solved this problem.
Thank you.

Denis, this is caused by your change here: https://github.com/LimeSurvey/LimeSurvey/commit/aa287360a6f171009e0df44999a2da30eea71eb9#r47190978

I think it is unwise to check for permissions here. This causes that nobody can read plugin settings.

A plugin should check permissions by itself.

https://bugs.limesurvey.org/view.php?id=16910

This function must be protected : all public function in plugin can be called without any control … by url directly …

This causes that nobody can read plugin settings.

But : there are a permission setting for this …

The 2 functions must be private or protected , set it as public are a major issue

I revert the fix : https://bugs.limesurvey.org/view.php?id=16910#c60987

But … maybe we need to move this 2 fuicntion to protected in 5.0 ?

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=31105

Fixed in Release 4.4.9+210219
