My Navigation Collapsed Hamburger menu won’t show in the Pro’s editing window and it only shows this:
“This element could not render due to invalid template markup. This could be due to changes introduced by a third party plugin. The front end of your site should still function normally.”
I noticed it and upgraded my Wordpress and Pro theme, so I’m now using 2.5.5. After updates I have deleted my cache.
I tried to delete the collapsed navigation and remade it scratch. It shows about an hour and then it switches back to the text. I’ve taken most of the plugins off, but it still stays the same.
Thanks!
