I went through and deactivated all of the plugins except for the Eventbrite one and it didn’t resolve the issue. I switched the theme and deactivated the plugins and still showing the 404 page or oppose there’s nothing there copy.
I tried what you said. (Deactivated plugins, switched to an unmodified theme, and visited the permalinks section….) Then I reactivated the theme, and turned the plugins back on and ran into the same problems…
