Joomla Templates - j Quark Template won't save in Jommla 3.5.1

I made changes in Helix J Quark template but when hitting any of the buttons "save" "save & close" Save as Copy" ect nothing happens. I have to hit the back button to get out and nothing is saved.

Any suggestions?

Thanks

Hi, 

There seems to be an incompatibility issue.Please go to 'plugins\system\helix\js\admin\layout.admin.js' and on line 143 just remove ' return false;'
