I do it, i disable de free version, activate the pro version, and then delete the free version, and is the pro version is not working.
When i tested on the free version, everythings works fine, now on the pro version, the sidebard is not working, everything is attached to the left margin and the pagination is not working, you can check it here: http://www.bodybuildinglatino.com/preguntas
i have the same problem, have to disable the popup JS in order to work, you are going to fix this or the ppl that have a lot of plugins cant use that feature of your plugin?
