Posting Bug

Everytime I make a post, my browser, when it reloads the dashboard, brings nothing up. I can refresh, and even clear my cacher, cookies, etc., and it still wont bring up content. The post has been made, but my admin panell, and even going to the blog itself, renders nothing but a blank page. I have to close the window I had open (all the window, not just the specificc taab – Firefox), clear my cache, then reopen a window to get it back up working properly aagain. This happens everytime I attempt a new post, and it is getting very annoying.
