Trying to go from 4.7.0 -> 4.7.4
As soon as I set php from 7.4 to 8.0 I can no longer access the AdminCP and get this error (below) and cannot go any further. Reverting to 7.4 is the only way for me to access the AdminCP again but the main site is fine.
[[Template core/admin/global/globalTemplate is throwing an error. This theme may be out of date. Run the support tool in the AdminCP to restore the default theme.]]
Tried going into theme editor and restoring default theme and setting as default.
Tried clearing system cache.
Tested alternate browser in private/incognito.
Tried disabling customizations but every time I go back to check it or try disabling again it keeps saying "Non-default theme"
Not running any 3rd party applications. Just system and forums.
System log shows this error:
TypeError: Unsupported operand types: string + int in /home/tactinep/public_html/forums/system/Dispatcher/Admin.php:587
