Same problem here. Have only made the site a few days ago with 2.5.1 and now blank pages when ever I save or publish anything. Very annoying. Will probably have to rebuild site because I don’t have time to mess around.
1. Have never even activated plugins in the first place.
2. Have deleted the “active_plugin” row wp_options as suggested by other threads
3. Am only trying to post very short posts
Anyone got any suggestions??
