If I download and enable version 2.0.0, then navigate to `/admin/people`, I get the error message below (I removed my database name since it wasn't relevant). It seems the table isn't created when the module is installed -- `allowed_languages.module` is empty. After applying the code in patch #17 to that file, then the module works fine.
The error on my site:
The website encountered an unexpected error. Try again later.
