LimeSurvey version: LimeSurvey Community Edition 7.0.4+260620 (DB version 708)
Own Server
Survey theme/template: Vanilla
==================Hello,We are having serious issues after upgrading our self-hosted LimeSurvey installation from LimeSurvey 6 to LimeSurvey 7 using ComfortUpdate.Current version:LimeSurvey Community Edition 7.0.4+260620 (DB version 708)Environment:

• Self-hosted installation
• Apache 2.4.68
• MariaDB 11.4.12
• PHP 8.1
• Linux server
• Using the classic editor
• Production environment with many users and approximately 60 active surveys

Because this is a live production server, we cannot easily perform drastic tests, reinstallations or major changes.Problems observedAfter upgrading from version 6 to version 7, several administration functions stopped working:

1. Question groups in the survey structure cannot be expanded.
2. Clicking on groups or questions does nothing.
3. Questions and groups cannot be reordered because drag and drop does not work.
4. In dropdown/list questions, answer options and subquestions cannot be deleted.
5. Several buttons and interactive elements are displayed correctly but do not respond when clicked.

Interestingly, right-clicking a group or question and selecting "Open link in new tab" works correctly, and the question editor opens normally.This suggests that URLs, permissions and editor pages themselves are working, but some interactions in the administration interface are failing.Already tested

• Chrome, Firefox and private/incognito mode.
• Different users.
• Existing surveys and newly created surveys.
• Clearing LimeSurvey cache.
• Deleting and regenerating
  Code:

  /tmp/assets

  .
• Clearing
  Code:

  /tmp/runtime

  caches.
• Running Data Integrity Check, with no relevant issues found.
• Testing both
  Code:

  urlFormat='get'

  and
  Code:

  urlFormat='path'

  .
• Enabling debug mode.

The issue persists.I have also found another discussion in this forum describing a very similar problem with the survey structure editor after upgrading to version 7, but unfortunately it does not appear to have been resolved.Has anyone experienced similar problems after upgrading from LimeSurvey 6 to 7.0.4+260620?Could this be a known regression affecting the classic administration interface?
Any ideas or safe workarounds would be greatly appreciated, especially since this is a production installation with many active surveys.

I had the same issue yesterday on my Git/dev version.
I checked again today: I have the same issue, need to reload the question page multiple times to fix.
Can you report the issue, please?

Else: you update a major version without testing?
