If the plugin isn't doing what it's supposed to do, try some of the following topics to solve your problem.
The plugin can automatically log deprecated warnings to the console whenever you're using a deprecated option or event. Include the "debugger" .js file AFTER the mmenu .js file in your webpage.
<head> <script src="path/to/mmenu.js"></script> <script src="path/to/mmenu.debugger.js"></script>
Most of the time, the debugger will not only tell you what's wrong, but also how you can fix it. You should probably fix these issues as soon as possible.
If you have a question about how to use the plugin in your project, try asking it on stackoverflow.com. That way a whole community can help you.
