Make sure when you uglify the JS, that you turn the mangle option off. I turned that off for all of my vendor scripts: .pipe(uglify({ mangle: false }))

Ahh, I'm tired and I've read "sass" instead of "js" . I'm sorry. I'll check it and come back to you.

No error messages. The SASS works fine, just the JS files when I use Gulp. It's so weird actually. When I reference mdb.js via a <script> tag it works fine. But if I combine jquery.js, bootstrap.js, and mdb.js into one js file, that is when it messes up. After trial and error, I realized it was the mdb.js (mdb 4). However, this may be a gulp error. Perhaps there is code in the mdb.js file that gulp cannot handle and therefore messes up when you try to concatenate files rather than referencing all three separately with <script> tags. But I thought I would pass on the information to you anyways :-)

Hi, thank you for nice words, I'm happy you find MDB useful. About the issue: any more error messages? I compile MDB scss files via Gulp without any problems.
