I moved a Joomla 1.5 site to free hosting site. I got a security error.
I contacted the hosting company and they sent me to a link to fix it. I added “@” before these three lines in the Libraries >> Joomla >> Sessions folder sessions.php file.
// You find these first two around line 105
//set default sessios save handler
@ini_set(‘session.save_handler’, ‘files’);
//disable transparent sid support
@ini_set(‘session.use_trans_sid’, ‘0’);
//This one is on around line 685
//sync the session maxlifetime
@ini_set(‘session.gc_maxlifetime’, $this->_expire);
