you can manually apply this modification to your forums now, or wait until the next version of UBB.threads is released when it will be included.
Thank you for the fix.
When you say next version, are you referring to 8.0.1? or 8.1?
UPDATE: If the cache gets inadvertently cleared for some reason, shouldn't there be a check in the code that says if the cache value is NULL set to the current date? When I looked at my cache yesterday, the cell was empty. I assume that's because the cache was cleared. Your fix prevents the cache from being cleared, but if it were ever possible to set it to empty again, the problem would reoccur, would it not?
