Is there a possibilty in a bric to say the blocs App that the extension should be automatically changed from html to php?
Yup, it’s already in there. Look in API Calls - pageSuffix
Ahh yes, thank you
Be aware, if that’s a Bric someone else than you should use, and it’s installed on an existing html page, all links to that might be lost and redirected to the new php page.
