Problem with admin interface landing page

[sternchen]

Hi everyone,
first of all thank you very much for the new version. I just did the upgrade and it looks good.
I have a problem since my provider upgraded PHP from version 7.3 to 8.2 already while ago, but it didn't bother me to much.
My landing page after login (http://***.de/serendipity_admin.php) looks like this:

After clicking on some draft I get the normal landing page with side bar and I have access to all settings etc. It's really just the landing page after login, which looks strange.
I thought it would be fixed with the upgrade, but unfortunately the problem remains.
Any idea how to fix it?
Thank you very much and kind regards,
Falk

This looks like it loads the old admin interface. Is that normal for you? Does your backend usually look like this: https://www.onli-blogging.de/uploads/s9 ... d_tiny.png ?

Yes exactly, it looks like yours.

A while ago there was a plugin that changed that page, could be called serendipity_event_dashboard. Something like that installed?

[sternchen]

Oh yes great, that's it. The serendipity_event_dashboard plugin was installed and active. Moving it to inactive fixed the issue.
(Probably I should check all my plugins, there is some really old stuff)
Thank you very much!

Maybe better to uninstall that one even, as its old code might cause issues with future PHP versions. And as it was aimed at s9y before the dashboard was useful, I think, it is unlikely to get new updates.

Great that it works now though :)

Yes I uninstalled this plugin and found some more old stuff ("Karteileichen"). Deactivating some of these is causing issues, but I will do some more maintenance first before I maybe ask for some help again.
Thanks so far!
