When I make changes to an existing event (adding a new speaker, for example) and update it, it shows up fine in Firefox but does not appear in Safari or Chrome (on Mac or PC). This happens for multiple people viewing the site on different computers. We have all emptied our caches and reloaded the page.
Any ideas how I can fix this? At the moment, I have to delete the old event and add a new one (with a different slug). Not an elegant workaround.
