For some reason, on 3 separate and different installs of wordpress, i cannot save a post, page, or quote (quote plugin) containing the word "mother" anywhere in the title of body. There is no variability in the length or general content. As soon as i place the word mother in the entry i get a 404 error on save, save and continue editing, and publish. This is the ONLY time i have a problem.
How could there be an issue by just having "mother" in the post? The 404 error is not the wordpress 404 but the generic apache 404. I've tried this with all three installations of WP, as well as a freshly downloaded install (default everything and no plugins) with the same result.
