It recently came to our attention that prior to releasing the 2.0.3 build, we inadvertently changed the webcal feed version number in the Events Calendar PRO plugin code. This in turn made it impossible for some users to import their events into external calendars (google calendar or iCal) without seeing an error message telling them “iCal (or other) can’t read this calendar file.”
This issue has since been patched in the Events Calendar PRO 2.0.3 code and a hotfix deployed for any new downloads. If you experienced this issue, just re-download the 2.0.3 code and you’ll be all set. We apologize for the inconvenience along these lines and will make sure this doesn’t get reverted upon releasing 2.1.
