Pretty sure problem started after updating from 3.4.1 to 3.4.2 as I haven't done anything since updating.
Whenever I try and load /wp-admin I get the following: "Fatal error: Cannot run code from this file in conjunction with non encoded files in /home/content/71/7820071/html/hbb/wp-includes/version.php on line 371".
Every other attempt it will just load the "500 Internal Server Error" page.
When trying to load just the site itself it will initially load the "500 Internal Server Error" but upon refreshing it loads the site fine. Does this with every page I try to load.
I've tried renaming the theme I'm using (InStyle) and reverting to default, but no go. Also done same for plugins, no change.
Have also tried replacing all the wordpress files (except wp-content) with fresh ones -- as well as the previous version -- and nothing.
I'm all out of ideas... please help!
