Hi, since local update and Wordpress update, I have this fatal error and cannot acces to the site or admin >> Warning: Illegal string offset ‘capabilities’ in /Users/mikaelschireff/Desktop/LOCAL/app/public/wp-includes/class-wp-roles.php on line 290
//I find this topic with same problem but no solution >> Fatal error : Cannot access offset of type string on string in "class-wp-roles.php" on line 290
my skills are too limited and i don’t know what to do, i went back to an old version of Wordpress 5.8.3 and an older version of php 7.4.1, now i see my site but cannot access the admin , how can I do ?
Thank you for your help.
