I haven't had this error recently myself RR but from past experience it typically means there may a problem at the host server's end. Normally it's a brief glitch and rights itself. One thing I can suggest to try pressing Ctrl and F5 together (super-refresh). That refreshes your brower's cache just in case the browser hasn't done it automatically. If that doesn't make any difference then it's most likely a problem with the host server. I'll have a chat about it with WP tomorrow.
If others are experiencing similar error messages to Rodger then let us know.
