Double slash cause minify problem

When adding your scripts to the page, there is two slash between ‘starbox’ folder and ‘theme’ folder.

E.g.
http://www.domain.com/wp-content/plugins/starbox//themes/business/js/frontend.js?ver=3.0.2′ (JS)
http://www.domain.com/wp-content/plugins/starbox//themes/admin/css/hidedefault.css?ver=3.0.2 (CSS)

This behaviour causes problems with the Minify library used by multiple cache plugins:
WP-Rocket, W3 Total Cache, WP-Minify, etc.

Thank you
