You’re probably here because you got the jQuery error “Uncaught ReferenceError: Velocity is not defined” after implementing Materialize into your WordPress site.
The Good news is this is a simple fix so you can get right back to it! 🙂
The issue is that WordPress defines jQuery in no conflict ( jQuery ) and Materialize defines jQuery with the dollar sign ( $ ) so when materialize.min.js is loaded you’ll need to change out a line of code in the file to get it working correctly with your WordPress site.
Once you’ve added the materialize.min.js file to your site, open it up in a text editor or whatever FTP editor you use and do a search for this code
Vel=$?$.Velocity:Velocity
and replace it with this code
Vel=jQuery?jQuery.Velocity:Velocity
Once you do this, you should be all set!
