@request - cache files need to be reduces for cpanel machines

The Cache Files need to be reduced for the xoops_data folder, this is quite easy to do some example basic work around routines are included here to be worked into XoopsCache::read(), XoopsCache::write() & XoopsCache::delete().

XoopsCache::read() in class/cache/file.php
