I enabled dbm protection in the admin panel and it worked at first but now I always get this error: Fatal error: Call to undefined function: dba_open() in /home/sites/home/web/amember/plugins/protect/dbm/dbm.inc.php on line 16 - I assume I'm missing an include file somewhere? Or do I need to do something else for dbm protection?
It mean that your hosting has not necessary PHP modules to maintain dbm files. WHy do you need "dbm" ?
