Horizontal scroll problem the7 theme

I am looking for a solution how to remove the strange horizontal scroll on my webpage that I made with the7 theme.

When I spoke to support, they solved the problem in one of the versions. But in a later version it came back. Its on desktop and mobile. and is you use a touchpad or a touch device you can swipe the whole website away.

Does anyone know of a solution?

With kind regards,

Try removing the jquery file that calls the horizontal scroll located in your functions.php file.
