Open portal extension modification needed for Joomla! 3.4 compatibility

The Joomla! open portal extension needs a slight modification to be compatible with Joomla! 3.4.x

In the file /administrator/components/com_advancedopenportal/controller.php around line 18 needs this:

function display($cachable = false) 

to be changed to this:

function display($cachable = false, $urlparams = false) 

Hope this helps someone. If I find anything else, I just installed it and haven’t test driven it very far yet, I’ll post it here.
