I'm trying to update to 2.7.0 from 2.6.1.
I've done this on one website we have, but the other just isn't playing...
I'm doing the exact same thing (And also tried this 3 times and still getting the same issue) It gets to the point where I agree to the terms & conditions, then goes to this URL:
http://website.com/admin.php?C=wizard&M=do_update&language=english&ajax_progress=yes
And displays a Google Chrome error:
Server error
I normally see these errors when there is a missing DB file, or an error with the DB. But I've restored it back, ensured the CMS worked, then tried again and it still doesn't do it.
Console isn't showing anything neither.
What could be causing this?
