Hi!,
In the above combination of Joomla, php and Admin Tools the administrator login doesn't show up and an error message is shown:
"in_array(): Argument #2 ($haystack) must be of type array, string given".
By enabling/disabling the Admin Tools extension I'm pretty sure the problem lies in the extension. Probably user action logging?
So the question is: is Admin Tools 7.0.4 ready for php8?
Best,
Arie
