not able to edit pages.

hi all

i know this is a word press forum and my question is about mystile (i think) but wootheme don’t like giving every one support just there paying customers.

any way i have site http://www.mypouch.co.uk using Mystile theme which is working fine. however for some reason in the last two days i can not edit any pages when i click on pages from the dashboard i get redirected to my site with a Error 404 – Page not found!.

so i changed to the default theme and all is fine. how i can i resolve this issue as i need to edit pages and add new ones etc.

thanks

Neil
