Latest Version Of Cs-Cart Not Working With Php 7.4


Trying to update the PHP on one of my sites to PHP 7.4 - but when I do the backend just returns a white screen. The front end works fine, only the back end it affected. Using latest version of CS-Cart

Any ideas? Thanks

To add PHP 7.3 works fine

When changing php version you need clear cache and restart Apache2. Check also if you are using any Redis, apcu… and you have their modules installed for the correct php version
