Deleting Posts/Threads

Hy

Since today is not possible to delete a post or thread we get errors:


Fatal error: Call to undefined method vS_HHR_Engine::rebuild_cache() in E:\inetpub\vhosts\efef.dyndns.org\httpdocs\vb35\in cludes\functions_databuild.php on line 1065


PLeas help, we need to stop the forum



Edit: Sorry abou the posting, i found the error, it was a old file edit from a previous version.
