There is no frame on the supplier registration page

Hi there,

1) This is very dependant on your theme - it will be different with each theme.

I would suggest:

-> Try to edit the page and see what kind of template options there are:

for example with the Flatsome theme I have many different page styles here:

Some of them are full width (no frame), but others have sidebars, margins, etc.

2) Another option is to add this CSS to your site:

main#main {
    margin: 2% 11% !important;
}
header.entry-header {
    margin-left: 0px !important;
    padding-left: 0px !important;
}

It will make it look like this:
