I have a prophoto4 wordpress blog with over 50 posts and 10 pages. Lots of pictures.
I've just changed my permalinks to /%postname%/ and my entire site has crashed. I can navigate around my dashboard and back-end but can't access posts or pages. I go back to settings -> permalinks and the page is blank.
Help! At this point I'd be happy to restore the settings to what they were if it means the site will work!
I'm not very techy, so help in lay mans terms would be much appreciated.
