Not sure that all oxwall site has such problem. As I see you have customized your theme by yourself. And after customization, you have losed some javascript. Would you check what did you changed and roll back some changes?
Addenster, we had to do a full back due to the failure of upgrading the software. We used the very same theme before the upgrade and it worked. We're still using the same theme and it doesn't work. I also upgraded the theme and it STILL doesn't work.
