Sorry for the delay in reply; I still haven't resolved this problem.
I tried re-saving the recurring event, and also trashing it and creating a new one. Still the same problem.
On the recurring event edit page, it says I can edit individual recurrences from the events edit page. However, the events edit page does not list any of the individual recurrences, so I cannot see how to edit them.
My test settings are: weekly event (every Wednesday), from 1 June 2012 to 1 June 2013. The event title is "Weekly workshop". From the recurring event edit page, if I hover on "View post", the link says it will go to:
But when I click on the "View post" button, it redirects to
i.e. the first recurrence within the defined dates (but note that this is in the past). But this page results in a 404 error, as do all other recurrences listed on the events index page (i.e. http://domain.com/events/).
