You’ve posted the same question a few months ago which I replied to here:
The theme has no plugin conflicts that I know of.
Is this the blue bar you’re describing?
If yes, then same as my reply on the linked comment, just deactivate the mobile theme module on your Jetpack plugin.
If I were to guess then I think your issue is caused by using both Jetpack’s Mobile Module and your caching plugin (wp-super-cache).
It asked me for the URL but then it doesn’t seem to show it.
It’s not visible on the front-end but I can still see the URL you entered.
