Unfortunately, they are not compatible with XOOPS 2.2 and/or PHP 5. But dont' worry ! The SmartFactory will soon release new versions of all its modules to support XOOPS 2.2 and PHP 5 ! We will also be releasing a completely new module named SmartTie that will allow you to link any objects of any module within your site ! We are currently taking a small break for the summer vaccation, but we will be back in action on the begining of August ! So, the new releases could be expected during the first week of August ! So stay tuned for new releases ! Cheers !
