Hi @palcarazm ,

I am not familiar with GitHub. 😵

I have tried to fork your repositorie palcarazm / bootstrap5-toggle, but GitHub say 'No more forks can be created. These forks already exist.'. I don't know how to sync my bootstrap4-toggle fork to your bootstrap5-toggle. 🤔

[palcarazm]

Okay, don't worry. I will merge your changes and put you as co-author of the commit.

[DarkNami]

Thank you. 👍

[palcarazm]

Done! It will be released in the next patch.

[DarkNami]

I have tested it, warning is stopped.
Thank you.
