Registration page is not working

Hi, I state that I have no particular experience with OJS.
My problem is when a user tries to register: clicking on Registration button, nothing happens.
I’m using the default theme.
My error.log doesn’t report errors.
I really appreciate your help, thanks.

OJS current version:
OS Linux
PHP version: 7.4.11
Apache 2.4.38
DB Mysql 8.0.23

Hi @weroiss
Can you provide the URL of the installed OJS?
