I am getting an "Error 500" whenever I access ANY php file on my wife's site. I asked her if she made any changes. The only thing she could tell me is that she may have made an update to a plugin.
I can't access admin or anything else. I renamed the plugin folder from FTP, that didn't help. We have a VPS account with Jumpline, they won't help us but said they didn't put a block on our site and didn't see anything obvious that was wrong with it.
