JavaScript Error On Login Page When Plug-in Is Active

So I’m having an issue with my Front-End login form. BUT only when I have a specific plugin enabled for user post submissions.

This problem only occurs when I have the user submitted posts plugin active.

The issue is: When users try to login using my login form, the form does not submit. It will appear fine and I can type in the fields but the login button does not submit. Users can still register new accounts. They just cannot login to their existing accounts.

After analyzing the page with DevTools, the error reads:

Uncaught Reference Error: FALSE is not defined
at HTMLFormElement.<anonymous> ((index):503)
at HTMLFormElement.dispatch(j.query.min.js?)
at HTMLFormElement.v.handle(j.query.min.js?)

I know that the simple solution would be just to not use the plugin and find an alternative. I’m just hoping one of you can help me if this is a easy-fix problem.

Thanks for your time!
