APS installer uninstallation problem
When I was trying to uninstall previously installed APS package, I got this error: Fatal error: Call to a member function intval() on a non-object in /usr/local/ispconfig/interface/lib/classes/aps_guicontroller.inc.php on line 325
I have looked into the problem and been able to fix the issue.
There was a missing "global $app;" in the deleteInstance function in the above mentioned file. After adding the global everything works fine.
