Can't Reach Back Office

[OttawaTitans]

Was having some issues that led me to ask my hosting company to downgrade PHP to 7.2.

Now I can't reach the back office.

I can log in, however the page I reach (see attached) goes nowhere.

I am very new to this and any suggestions would be greatly appreciated.

Hi

This screenshot comes when there is any error or warning in response and it not redirect to dashboard 

you can disabled debug mode if enable from config/define.inc.php by finding like 

        if (!defined('_PS_MODE_DEV_')) {

            define('_PS_MODE_DEV_', false);

        }

false means disable 

true means enable 

you can make it false if true and check by login again
