Hi @michalczajka,

I hope you are well today and thank you for your question.

It seems you are not using Unite theme on your site so i have moved your topic from Unite theme forum to other forum.

I visited your site and the space displayed at the side of your site content is not 10 cm as shown in the attached screenshot.

Have you managed to reduce it?

Best Regards,
Movin
