I have recently updated PHP to version 8. Ever since, I find that I am unable to update or install any extensions in Joomla (regardless of which extension it is).
When trying to update, I get no specific error (not even when error reporting is set to maximum) other than this:
Code: Select all
An error has occurred.
0 Illegal offset type
Code: Select all
fwrite(): Argument #1 ($stream) must be of type resource, bool given
I am running the latest Joomla version 3.10.11.
Can anyone please help resolve this issue? Thanks!
