I think I might know what is causing the problem. There was a similar issue reported with the recent update (4.9.0) . I've already finished the next hotfix version, it's waiting for approval on codecanyon.
I'm attaching this new version to this reply, please install this one instead, I hope this fixes the problem. (just deactivate and delete the one you have and install this one instead)
