Unfortunately "Rebuild Tag Cache" generates Error 500 during rebuild with 5, 100, 250 or 1000 records per cycle. This problem is not related to our server because we run dozens of scripts/rebuilds and some of them took a few hours to complete without errors.
Old tags are not shown in my discussion board and current Advanced Tags & Prefixes doesn't work because "Rebuild Tag Cache" generates an error. How do I fix it?
