Provide a link to your website so we can diagnose the issue.

For some reason your website has this style;

padding: 0 30px;

That is different from the theme’s demo website.

Try deactivating plugins to explore whether any could be responsible.

Thank you so much for answering.
Can you check out what is the right style?

I have, but first can you deactivate your plugins to explore whether any are responsible?

Well actually it didnt make any difference..

Is there a section in the dashboard named, “Custom CSS”, “Custom Styles”, or “Jetpack”?

Custom CSS yes.

Add this to it;

#menu-secondary > .wrap {
 padding: 0;
}

Thank you very much!!! Wow, very fast help!
