[solved] Message security error

[inspectorflint]

Thanks, Joe. I change the php version to 7.4, and the issue repeats again.

I finally solved it comparing the files in the root directory of this Corebos with a clear instalation, and I discover that cPanel create three custom files, .htaccess, user.ini and php.ini. When I delete the three files, it works. I can log in and the security error disapear. Now, I try to update to last version

Regards, and Merry Christmas!
