I need to translate./change the RSVP above the ticket form and also the Confirm RSVP text on the submit button. Both are not in the dutch .po file. I myself had to look up what RSVP meant, so I think a lot of attendees won’t know the meaning of it either ;).
Ok, so because this is about the Tickets Plus plugin I checked the po files from that plugin and not the po files from the regular Tickets plugin. The strings I needed are in that file.
