Forms not working Help

I have this form with the submit button, after i click submit it goes for a page with url

localhost://admin/config.php?display=mypage

And this page says “Page not working” localhost cant process this request

i guess its because of the attribute action in the form, but i already tried to disable it and after click submit i cant create the item that im supossed to create with the form

Have a great day

Howdy! Welcome to the forums.

Are you developing a new module named “mypage” ? How did you get started with the skeleton of the module ? Cloning an existing repo that is closest to your goal is probably one of the easier ways to get started with “new” open source module development.
