Error code issue reported 2 weeks ago

This is a copy of a post on the time.ly forum that has got no response in two weeks.

We’ve been successfully using time.ly at this site scoremetronj.com for months. Recently the people updating the calendar noticed that they couldn’t view calendar events in June and beyond. The error message is:
Something went wrong while fetching events.
The request status is: 404
The error thrown was:
Individual calendar events can be viewed from within the event pages but going back and forth among the events is not working correctly – the events don’t appear in date sequence.
The plugins have been playing nicely together up to now – this issue has appeared only recently (within the last week).

I’ve tried manually deleting and re-installing the plugin but this did not solve the issue and in fact blew up all the formatting – I had to roll back my backup to before the change.
