Hi, I have MDB 4, and want to download the Double Navigation with hidden SideNav under fixed Navbar (this is MDB 4 Pro, jQuery). But when I want to download, the system tells me I should get Pro... I have already paid for that. Your System knows me under What is wrong there?

BR, Eberhard

We know what's wrong with tabs/pills... and other components using MDBNavLink but we need to implement the solution and test this fix. In this case, there was a problem with the react-router library. We've found that the problem only occurs locally. If you put the project on the web, everything should be ok.

We're currently working to resolve the issue, but one of our users has implemented a temporary solution. Mabe this fix will help you with your problem.

I will paste its temporary fix below:

A temporary fix would be to remove all active classes using JavaScript, and then >setting the active manually. This can be achieved by using React DOM References (like Ref={this.tab1}) and then removing all classes using removeAttribute("class") on >this reference. Then setting the previous classes + active if used.

Best regards,
