A cache has been implemented to improve site performance, but that means your edits won't be seen right away unless you purge the cache whenever you make those edits. This is for all content including calendar updates.
Please note: The purge cache button is only visible to Admin accounts. Therefore, no other user type will be able to perform this task.
This is the button you will be looking for, at the top of each page (frontend) in the blue toolbar.
When to purge cache:
1) When you edit a page in the backend dashboard, either using the WordPress editor or Themify Builder, save changes as you normally do then navigate to the frontend of that page and hit button.
2) When you Turn on Builder through the frontend, save changes as you normally do, then hit button.
3) When you add a new event or edit an existing event in your calendar using the RJ Web Builder calendar plugin or through google and a scheduled import, and the event does not appear right away, navigate to the calendar page and hit this button.
