Hello. I am having a problem which that my Odoo has two websites and a custom addon I developed but, while it works in the first one, in the second, does not.

My custom addon inherit the website and changes it. The second website also uses that addon but if I modify it, the second website does not change unlike the first one.

Is the second webpage using a clone of my addon? Do I have to do something special to make it work?

Thank you in advance.
