So the short version is my company was brought in to manage IT matters for a client and the previous IT personnel refused to hand over any information, logins, etc. I spent the next 6 months trying to figure out what I was dealing with and fixing the utter catastrophe left in the wake of the previous staff's departure.

The client's website was a secondary concern since there were more pressing matters and the website worked well enough.

Well, now the website is finally in my sights and I need to bring it up to speed. As it turns out, the site is concrete5 running on a version of XAMPP that's at least 5 years old.

After many hours of headaches, I successfully ported a working copy of the website to a VM so I can attempt to tinker without blowing up a production site. I have run into a hurdle. The current version is 5.5.2.1 and any attempts to upgrade the site to 5.6.3.4 result in every single page reporting "Page Forbidden". I can't access anything except , which does nothing.

I've attemptedhttps://www.concrete5.org/community/forums/installation/page-forbidd... among other suggestions here on the forums to no avail.

Any help would be greatly appreciated.
