I'm performing a test upgrade of my latest Xenforo on a clone server. I successfully upgraded php from 5.2 -> 5.4.15 and the other test server details are as follows.
Apache version: 2.2.24
MySQL version: 5.0.96-community
After upgrading the site, I'm getting "An unexpected error occurred. Please try again later." on the site.
I've few questions:
1. What's the right way to fix that error?
2. What's the latest MySQL version I can upgrade to without worrying about errors.
3. If there are issues running 5.4.15; which is the latest PHP I can upgrade to without worrying about errors?
