Our firm runs several websites based on WordPress formats. This past week, we've seen a number of 500 Internal Server Errors and slow loading times as we've been trying to work in the back end.
That I know of, it's only happening on two sites, Central Florida Ag News (running WordPress 3.5.2) and Florida Blueberry Growers Association (running 3.3.2), and usually only when working in the back end. Both run different themes, so I don't believe it's related to that.
I've seen the advice to check the error logs on the server, but ours was last updated February of 2012.
Any suggestions for how to try and clear this up?
