I decided to first roll my PHP back to 7.2 (since I know I did use this before and support is available for free) and went into maintenance to do some checks.  First ran 'Reinitialize integrity check' with no problem, then 'Repair and optimize database' with no problem, and finally 'Update photo information'.  This fails.  Snippet of output below:

Notice: Undefined offset: 1229 in .....photos/admin/include/functions.php on line 1313

Notice: Undefined offset: 1239 in .....photos/admin/include/functions.php on line 1313

Notice: Undefined offset: 1241 in .....photos/admin/include/functions.php on line 1313
this continues thru offset 1576 followed by

I'm thinking something got seriously messed up with the Piwigo upgrade followed by the PHP.  I'll wait a couple of days for other ideas.  Unless I hear otherwise I'll probably just remove my install and start fresh because I have over 800 albums/sub albums and probably over 100k images.

OK so I moved my install to a temporary directory and started a fresh 14.4.0 install with PHP 8.1 selected.  Patched issue #2150 and then connected.  Copied my existing pictures from the temporary directory to the fresh install directory and then started a synchronize.  Probably a bad idea with how large my fileset is because it might exceed the run time I'm allotted for a process - the page just generated a failed to respond error message.

So then I go back to my website and login and I'm starting to see some of the albums and images (not all).

I try to go to the admin tab and this happens:  (sanitized for my security)

If I go back to the website entry point I can see some of the albums and images and I'm logged in, but I can't access the admin tab - it crashes the same way every time.
