Topic: Errors since renewing GitLab access and Pro subscription

AB free asked 4 years ago


I have recently renewed my pro subscription and access to GitLab repo.

Since then I have been facing a few issues.

While Installation,




have been unavailable. These MDBreact imports never gave any errors previously.

I used npm install and added it to my package.json manually.

Further, after starting the project, I have been facing the following errors on a few pages:

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. 
 You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.


Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons: 
1. You might have mismatching versions of React and the renderer (such as React DOM) 
2. You might be breaking the Rules of Hooks 
3. You might have more than one copy of React in the same app See for tips about how to debug and fix this problem.

All these issues started while I lost access to GitLab repo. I have tried reinstalling the project, creating a new mdb pro access token, going back in my codebase to older HEADs, but couldn’t find any solution.

Are these issues created due to MDBreact? Because that’s the only thing that has been changed in my code base.

(Also, Is the premium support available in my subscription? I have just renewed my subscription and I thought it included premium support too.)

Thanks, please help. Project on hold.

how to recreate your problem?

Ok to simplify,I created a new page with basic text. It worked fine.

I added 'MDBBtn' component and it threw the 'invalid hook call' error as mentioned in the main question. FYI I am not making use of hooks in my project.

I tried the regular 'button' tag, it worked fine. These errors are suddenly appearing out of no where.

Did you see this topic ? We are using 16.12 version of react/react-dom.

Got the problem solved. Deduped the react-dom version. This was never a problem before. Anyway, got it solved.

The other error still persists; I'll try to see why it causing it and get back with a specific question.
