A blank screen appears when I click the blue ‘Mega Menu’ button
This issue is almost always down to a plugin conflict. Conflicts with the following plugins have already been fixed:
- SlideDeck Pro
- Pinboard Theme
- AGP Font Awesome Collection
- WooCommerce Product Feed Export
- Profit Builder
Please check the nav-menus.php page source and look for any plugins that include ‘colorbox.js’ or ‘colorbox.css’ (just search for ‘colorbox’) and disable the plugin.
Otherwise disable all plugins and check to see if the settings load correctly. Then enable plugins one by one until it breaks again. Once you have identified the conflicting plugin please report the plugin to support so we can work on a compatibility fix.
