I updated all forums yesterday and it included a change in the cookie the forum sets in your web browser. Not all browsers would have been affected but if you are getting logged out after 20 mins or so then follow these instructions to the letter and you'll be fine.
1. Manually log out by clicking log out, this clears your existing cookie
2. Go to your web browser and erase all cookies (if you don't like doing this as it's saving some important login details for some other website then you'll need to find where your cookies are stored and look for ".tilersforums.com" and erase that (there may be more than one, if so, erase them all).
3. Close your web browser down so the changes take effect
4. Open it up and log back in the forum and MAKE SURE YOU CHECK THE "REMEMBER ME" BOX.
