Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
May i know what PHP version you running on your current site now?
If you already switch back that PHP version to 5 , then we need your CloudAccess login access so we can switch to PHP 7.1 and see what is the error you hitting.
And can you guide us how to switch the PHP version from CloudAccess and which page showing those error ?
By the way, I was unable to login on your site backend, this is what i hitting now :
Warning
