Hi,
With Tradus quickstart, I have an incompatibility with PHP 8 with the override de mod_login. With PHP 7.4 it's ok.
0
count(): Argument #1 ($value) must be of type Countable|array, null given
Function Location
1 () JROOT/templates/travus/html/mod_login/default.php:70
2 require() JROOT/modules/mod_login/mod_login.php:34
When I deactivate this module with PHP 8 it's ok.
