Save, Save and Close, etc. Buttons not working

You can try this solutions:

Solution 1:

Go to your administrator panel: System/ Clear Cache -> select items and then click the delete button.

Solution 2:

Go to 'plugins\system\helix\js\admin\layout.admin.js' on line 143 just remove ' return false;'

And then, please in browser settings clean all cookies and temporary cache and try again. Also, you can try incognito mode etc.

Thank you very much & Kind Regards,
