I seem to be getting this in a few areas and other misc errors when I upgraded from 2.0.13.1 to 2.2.2 via the Upgrade patch.

For instance, reading a news article, I try to add a notification to my Email when a new comment is posted. I recieve the "No valid security token found in session" error, then when it tries to go back to the news article, I recieved: "Sorry, the selected story does not exist." and it takes me to the news listing.

Any help would be greatly appriciated. I did this upgrade on my test box and all seemed to work ok, but I just did not find these errors before upgrading my live site, http://lifewithchrist.org ...

Thanks for any help,

Jeremy
