I found a way of changing the words “venue” and “organizer” using /httpdocs/wp-content/plugins/the-events-calendar/src/functions/template-tags/venue.php and /httpdocs/wp-content/plugins/the-events-calendar/src/functions/template-tags/organizer.php, but I’d rather make that change in a folder, so they don’t get overwritten when an update comes.
I’d also like to change the word “Events” to “Courses”. I tried free community support but noone answered.
Also, there’s a similar question about this, and the support said to use the functions file and add a filter, but I’d have no idea what the code is for that.
