Spiffy Calendar 404 Error After Installing HD Quiz

closed

After installing and activating HD Quiz, my Spiffy Calendar plugin stops working, and I receive a 404 error when trying to access the calendar functionality.

Please disregard my request. I was able to resolve the issue by re-installing both plugins.

Hi Sergey,
HD Quiz does not affect other plugins like this as it does not even have any front facing pages. So unless you have some weird custom permalink structure where the name of a quiz/page matches the name of one of your events/calendars, there should never be any conflict.

Your issue is probably an unrelated WordPress issue with permalinks. These things can usually be resolved by resaving your permalinks. This can be done by going to your WordPress Settings -> Permalinks page, and saving. Try this and get back to me.
