Hmm, let me check my mage portal addon and see if that has similar issues since the expansion.
We are doing things differently so at least if mine works I can point you to that to see what might need changing now in yours.
Okay, mine appear to be working.
I am using xml files to set up frame templates and frames
I am using the secure set up type/spell and Requesting spell data prior to setting up the buttons
And instead of using spell1 and spell2 for left and right clicking I am just using spell and having the teleport and portal buttons separate.
But whether these are why mine are working I don't know.
My addon if you haven't already tracked it down is :
