On a Wordpress based website, when I add text using wordpress visual editor or HTML source to a particular page - it gives "page not found error". I tried by adding some other text and its working fine. Then I typed all the text again and in between kept checking if it is giving any errors. Finally I am able to point to the exact word that is causing problem - from. If I put frm , rom or from it works. Only when I use "from" - it gives page not found error. Another thing, the error is only this page not on any other page. I have used "from" on many other pages and there is no problem at all.
Its a client website and I do not have access to the server. I only have wordpress login/password. Any help would be appreciated.
Update: I even tried HTML entities and it does not work. Right now we are using "fróm" instead of "from" as a workaround.
