Theme loading CSS from admin folder

It looks like there is an error on the theme so it tries to load part of the site through the /wp-admin/ folder.
I use the "UPFRONT" & FIXER theme

I'm seeing this:

Request URL:http://www.punchyour.com/wp-admin/admin-ajax.php?action=upfront_load_grid&ver=1.0.1
Request Method:GET
Status Code:401 Unauthorized
Remote Address:104.28.1.125:80

Request URL:http://www.punchyour.com/wp-admin/admin-ajax.php?action=upfront_load_styles&layout%5Bitem%5D=archive-home&layout%5Btype%5D=archive&ver=1.0.1
Request Method:GET
Status Code:401 Unauthorized
Remote Address:104.28.1.125:80
The source code show:

<link rel='stylesheet' id='upfront-front-grid-css' target='_blank' href='http://www.punchyour.com/wp-admin/admin-ajax.php?action=upfront_load_grid&ver=1.0.1' type='text/css' media='all' />

<link rel='stylesheet' id='upfront-main-css' target='_blank' href='http://www.punchyour.com/wp-admin/admin-ajax.php?action=upfront_load_styles&layout%5Bitem%5D=archive-home&layout%5Btype%5D=archive&ver=1.0.1' type='text/css' media='all' />

It looks like it is from the upfront CSS, how do I fix this ?

I'm using a user that is NOT LOGGED IN.

Thanks
