activation of payment section for fees

good morning. ECT* has a site for its events in Indico. Normally these are not chargeable. It happens that a recent one is instead … We generate the new pages using a template that we clone. So I did for Probing the CGC and QCD matter at hadron colliders (24-27 March 2025): Overview · ECT* Indico as well. Upon activating the payment section an alarm pops up

The question is, if I activate payments on this page, do they automatically activate on all events already published?
Thank you,
Barbara

It will only affect this event, and the feature is fine to enable in an event, since for any registration form within that event which does not have any fields with a price it does not matter whether the feature is enabled.

Thank you so much for your replay! all the best, Barbara
