HI brionny33!
I checked your website and I saw the below:
I think, your template don't access menu position,
because I create module custom and assign it on menu position,But It still can not display.
If I assign it on main-top1 positon. And I check module megamenu, it have result same.
I create a video, Please view it.

Thank you for looking into it Huyentt, but the menu doesn't look good on main top position, right beneath the slider in the home page and breadcrumbs in the other ones. Surely there must be a way to display your menu in menu postion? Would you be so kind to help me with this?

Thanks again

Dear brionny33!
I'm sorry,I don't help you for the problem. Module mega menu don't error. It is the configure of template,. You can check configure of your template.
Because module custom can't display on menu positon.
Thank you so much for sympathy
