Hi Guys

my saite started normally and from time to time after about 5 seconds appears a black band on the top almost covering, follows photo opening and then I noticed that when the zoom frazes appears the track appears that almost at the same time.
This problem happened only a short time ago and I have already tried and found nothing wrong with the site.
What could be causing this problem?
The problem appeared after some automatic updates.
Thanks for the feedback
Claudio
