HTTP 500 on setup create user

Do you still have the same logs now you have renamed and changed everything ?

Yes https://pastebin.com/WiCA6Xfm and same 500 in the apache log

When I turn debug on I get

Worked it out finally after upgrading to php 7 got a new error hinting to mbstring.

Turns out mbstring doesn’t come installed by default in cpanel/whm.

Thanks for the assistant anyways guys.
