I am getting a document expired error whenever I use the back button to go back to the Forum page from a Topic page.
To reproduce: 1. Visit a forum (e.g. https://forum.snitz.com/forum/Forum/Posts/118?pagenum=1) 2. Change the filter in the drop down box beside the New Topic button. 3. Click on a topic. 4. Press the back button on your browser.
I am guessing the way the drop down button works, you would have to resubmit it, if using the back button on your browser.
