Mobile homepage is sliding to the left

Suddenly, I do not know what I did change, the homepage on of my site hhtps:// is not fixed on my telephone, but you can move it to the left. All the other pages of the site are working well on mobile.
I spent a lot of time with checking all the text, boxes etc, but could not find it. Any advise to solve this little problem is very welcome. Thanks in advance!

Hard to say by just looking at the published website. Please send us the project via email ( to and we’ll take a look.

Thank you Duncan! After the latest update my homepage does not slide to the left anymore on mobile!
