Hi,
Looking over my previous support tickets, the only time I've seen this before is when a translation was changed to have a line break, like this:
Code:
"Upload, Share, and
Your Files"
Have you done any changes to the translations? The script should allow (or block) this however it can sometimes cause issues in the javascript.
If you still can't resolve it, can you raise a ticket with access to your install, I'll check it out for you.
Thanks,
Adam.
