i had the same problem and to be honest it is an easy one.. don`t mess with the database or anything else.. the only thing that is wrong is the PHP witch is set on SAFE MODE and the HCL has not been configured properly because the setup system that HCL has it`s very poor and a lot of things from config.php are not there.
so to be more specific.. to fix this problem just open config.php and edit this:
$conf['safe_mode'] = false;
$conf['safe_mode'] = true;
hope this will be usefull for anyone that encounters this problem. (worked for me any way)
