All of a sudden (I think after upgrading to wp 3.5) I'm unable to "Update" certain (not all) pages on my website. Instead, I get the following error message (on Firefox browser):
Your browser sent a request that this server could not understand.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
I've tried changing the Permalink options, but that does not change anything. The only thing that does work is if I delete the Page and then re-create it.
I've checked the other Forum postings on similar "Bad Request" problems, but none have a solution. Can anyone help?
