I am hoping that someone can help with my situation. I was running version 3.31.1 and used the Update tab in the panel to update to the latest version.
This happened SUPER fast ( 1 second) and reported that it had completed. However there were error messages above that. Sadly I didn't take a note of them.
I then tried to manually update by downloading version 3.34.3 and copying files by FTP. On first try about 70 of the files failed to upload, however after a few retries, all files were uploaded.
I went to the Diagnostics page and seem to remember that it looked okay, although there could have been some error text at the top of the page. As I was still running PHP version 7.x I thought it best to update to PHP 8.4. When I went back to the site it said "This page isn't working" and the Panel page was white with a single line and a box that says "X3.34.2".
I have no idea what to do next to get things working again. Any help would be very much appreciated.
