Hi, my site at sistersflowers.net has a malfunctioning nav button. It does not show up at all. I have tried all of the troubleshooting around plugin conflicts, updates (everything is current- wp, cornerstone, theme, php) and nothing changes. I have tried dozens of css additions, and the best I can do is this, which causes a gray box to show where the hamburger should be. This is clickable but no option to close and obviously a gray box does not really indicate that its a menu. Please help- I have spent two hours on this today with nothing to show for it but this gray box.
I will add a secure note with credentials in hopes you can take a look. Thanks!
