Cannot login to crm anymore (blank page)

When I go to my CRM (crm.xxxxxxxxxxx.com) I get stuck on “https://crm.xxxxxxxxxx.com/index.php?action=Login&module=Users” with a blank page.

I’m not sure but this happened shortly after this issue #78625.
I rolled back to a previous version after updating to 7.10 it was working than I upgraded again to 7.10 and checked if the issue was resolved (I continuously got time outs).

Now I am no longer able to get to my crm.

Any suggestions?

Thank you.
