Topic: I'm getting "multiple copies of React" Error
Element ref was specified as a string (ripple) but no owner was set. You may have multiple copies of React loaded. (details: https://fb.me/react-refs-must-have-owner).
Here's my code:

Hello again,
We've fixed this bug by updating our product to the latest React version and changing refs into ReactDOM in Waves component. Please delete mdbreact from package.json and add it again to dependencies like this:
"mdbreact":"git+https://github.com/mdbootstrap/React-Bootstrap-with-Material-Design.git#react-upgrade"
We'll fix it also in the next update of mdbreact in npm.

I am getting the same problem, in every component that uses this ripple effectjohn blakley commented 7 years ago
same hereMikołaj Smoleński staff commented 7 years ago
It's occuring because the lates version of React is 16 and mdbreact is based on 15 version. In the coming days we'll upgrade our product to the latest version.Tobiloba Adesanya commented 7 years ago
Thanks @Mikołaj Smoleński for the response. I actually updated the react package within the mdbreact package to React 16 although I am not sure if that made an impact.
