Superfish Dropdown Menu Not displaying 3rd tier or beyond menu items to non admin role users

Superfish menu works perfectly fine for Admin role users, on non admin and anon users can see the first level drop down, but nothing passed that.

If a menu goes "top -> second -> third" admin sees all levels, but a non admin sees only "top -> second"

In the actual source code if one views source on the page, the physical links and li tags are being rendered, but superfish is just not showing them when the user tries to interact.

I've checked and done the following:

• Verified that all affected user roles can see the content types/nodes associated with the menu items (they can)
• Rebuilt theme,js,css caches (several times)
• Rebuilt permissions cache (several times)
• Render Depth is set to -1

Other modules that affect menus installed on this site:

• Menu - core - 7.28 (obviously)
• Superfish – 7.x-1.9
• Menu attributes – 7.x-1.0-rc2+5-dev
• Menu Block –7.x-2.4
• Menu CSS Names 7.x-1.0-beta1
• Menu position 7.x-1.1

Theme is based on the bootstrap-business theme.
