Nextcloud version: 11.0.1.2

Updated from an older Nextcloud/ownCloud or fresh install:
Error occurs on both.

Where did you install Nextcloud from: zip file from nextcloud homepage.

Hotfix:
If you replace

throw new AutoloadNotAllowedException($fullPath);

in lib/autoloader.php:141
with:
return true; //throw new AutoloadNotAllowedException($fullPath);

You can use nextcloud with no apparent problems.

Can you please before the modified line add:
error_log(json_encode(debug_backtrace()));

[RincewindWizzard]

I tried to reproduce this today, but the error does not occur anymore.
I will message you, when this happens again.

[nickvergessen]

Thanks, feel free to reopen the issue, when it happens again.

I had the same problem,
after
return true; //throw new AutoloadNotAllowedException($fullPath);
I could access the admin pages
I uninstalled both office apps (which were not installed complete due to missing resources here) and now it works again

I had the same issue, the return true fix did work.
This happened right before the update 12.0.5 arrived. I don't know if this is a hint.
The error_log(json_encode(debug_backtrace())); added line did not do anything, where should I find the generated output ?

Edit : the upgrade to 12.0.5 resolved the issue.

nextcloud-13.0.2-r0 from AlpineLinux repository. Same issue.
Web server: nginx
Database: mysql
Hotfix from @RincewindWizzard fixed problem.

[sergiomb2]

'version' => '13.0.2.1',

same issue, after
return true; //throw new AutoloadNotAllowedException($fullPath);
I could access the admin pages

after in https://x/index.php/settings/apps?category=files I removed Onlyoffice app and
could put back throw new AutoloadNotAllowedException($fullPath); and all works now ...

NC 13.0.2
AutoloadNotAllowedException
Error should be displayed - not only logged -
it's a difference of administering NC or having access to the log files (which are nor really customer friendly to read )
I just had not only to disable but to remove disabled Bookmarks and OnlyOffice to access settings.
it would be great if this could be done interactively
in case of error - "Do you want to disable/remove [app-name] ..."

[mconway]

@ferdiga Thank you for this! I didn't have OnlyOffice but removing Bookmarks fixed the admin page for me. V13.0.6

出现这个问题的解决方案是因为：autoloader.php中的protected function isValidPath(string $fullPath)方法对于路径的判断，在windows中用\作为路径，但是循环中获取的路径是/，因此，出现错误。
