UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support RSS page not found

I had created an RSS feed option for a forum that was a fully moderated forum. When I selected under forum options to subscribe to the feed the software reports page not found. Other forums have the feed. The cache directory is there. I changed the forum from moderated to any logged in user can post and entered a test message, set cache time to 30 from 5. Still page not found. When I looked in the cache directory with my FTP client I found older files from April, a few from September. Not all forums have feeds. What would cause an RSS feed to fail? There was a time awhile back when my ISP was crashing the mySQL server. That required me to repair tables. Could another table be broken?

Oh and the RSS feed is marked as active. It is also a forum that is displayed on the portal page.

Try removing the files in the cache folder and rebuilding the cache from the CP

Let us know if that helps
