14.10.7 broken extension manager and search

Hello,

I upgraded xwiki from version 13.10.10 to version 14.10.7 and now I have several problems:

  • I can’t search on my wiki anymore
    Screenshot from 2023-04-11 14-35-52
  • The Manager extension doesn’t exist anymore and it seems that other features are missing
    Screenshot from 2023-04-11 14-36-07

Concerning the extension manager I wanted to do an import from the administration page as it is advised on the plugin page but this section does not exist anymore.

Have you seen a similar problem? I looked on Jira but I didn’t find anything.

Thank you.

Hi @florian-bellencontre,

Even if you upgraded from XWiki 13.10.10, there’s a chance that your instance was not initially a clean 13.10.10. It looks like there’s a Lucene plugin that is not recognized and looking at its documentation this is not maintained since 6.4.8.
The other error may be related to some custom code in the XWiki instance.
Finally, the Administration menus differences may be caused by XWiki progress, so please read the release notes between XWiki 13.10.10 and 14.10.7. https://www.xwiki.org/xwiki/bin/view/ReleaseNotes/

Hope it helps,
Alex

Thank you for your valuable feedback @acotiuga.

Indeed I read the release notes and I saw that the extension management system had changed to install extensions directly in WYSIWYG. The problem is that I can’t understand how the extensions can be uninstalled.

For example if I want to try to remove the Lucene plugin, I don’t know where to do it now.

In general when I browse I see more and more problems like this when I edit a page:
image

I have the impression that it’s actually my whole wiki that has been initialized wrong after the update. How can I try to initialize it again?

The error from the image says that the user that saved a page does not have the proper rights. You have this in many places because you did some changes in the wiki with non admin user. You may have dropped rights or removed user from the wiki.

It’s quite strange, I saved the page again with the admin user and it’s still there.

For the extensions how can I uninstall them?
