Menu Image version 2.9.0 changed the way it displays images, breaking compatibility with DevDemBootstrap3. DevDmBootstrap3 uses a custom menu walker but does not use the
nav_menu_item_title filter, so the plugin quit working.
One of my contract positions uses DevDmBootstrap3 for many client sites, so I wrote a basic plugin to get it working again.
To use the plugin, upload the PHP file to your
wp-plugins directory and activate the plugin. That’s it!
