Thank you for feedback us
I'm sorry but I'm trying to test the problem for you
I noticed that if you like facebook page page, popup shows up and you press like 1 or 2 times, everything will work well.
But if you do not like facebook page, when popup pop up, press the like button, the problem will occur
so i still have not found a solution to the problem, hope you can wait, i will try to fix it soon for you
Sorry for late replay, we have 1 holiday weekend
I'm trying to find a way to fix it for you, I'm checking that it's due to conflicts with other modules, modules that contain like buttons
