Hi,
I updated my Attitude Pro Theme from 1.7 to 3.0.7.
A greyed Responsive Menu appear in upper right near of my Linkedin link in Desktop Mode. The Responsive Menu does not work for Tablet and Phone mode.
For your information I switched to Attitude and it work fine! The Responsive Menu appear and work for Tablet and for Phone.
After updating to the latest version. Clear the all the cache browser cache, CDN cache, plugin cache and check it once.
Thank you!
