the mobile menu work post slide isn't work helping

the main problem passing true both noconflict calls.

jquery.noconflict( [removeall ] )
removeall
type: boolean
boolean indicating whether remove jquery variables global scope (including jquery itself).

so after calls code has not access $ nor jquery should getting errors in console.

if want use second version of jquery remove true noconflict call.

in general, though, bad sign when must use 2 versions of jquery in same page.
