XF 1.5 Any suggestions on pinning down this error?

[leslie dow]

My hosting company upgraded my VPS tonight and now I am seeing this error when I try to access my main installation and CP.

They are trying to track it down but if anyone has any suggestions this would be great. Also, my WordPress installation is giving a 500 error, or rather one of my WordPress installations is but one that runs on the same server is running just fine. Any ideas what these guys might have done?

Thanks
Leslie

Nevermind..looks like they fixed it. When they rebuilt the server they set it up to use PHP5.4 and not 5.6. so now they have fixed this and its all working. Or at least seems to be. Does that make sense to anyone? That this would cause a problem like this?
Thanks

An error like this would often indicate that MySQL wasn't running, though that's not definitive.

Thanks Mike, it turned out to be an older version of PHP. They provisioned the new server wtih 5.4 and not 5.6. When they installed PHP5.5 everything cam back on line.
It was an odd one.
So far its been stable today.
