javascript - Page content loads inconsistently without developer tools (F12) open in chrome -

puzzling me (probably hint solve), page loads consistently developer tools open. in chrome. see console error:

uncaught syntax error: missing ) after argument list 

could syntax error seen above cause inconsistent behavior? or else trigger such behavior. ok sharing more info needed.

my issue there 2 different versions of jquery loaded. after removing 1 of them issue resolved.
