Something strange has been happening to my site. Every so often, sometimes for hours, my site becomes unavailable to admin login. In Chrome, I get an error that says:
No data received.
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.
Other browsers it just loads a blank page when I try to login.
Sometimes it will show the dashboard after I wait for about 60 seconds, but then if I make changes and try to save them, it never saves - I get the error message again (ie. when working in my theme editor).
Any ideas how to fix this?
