Hey Phil,
Thank you for reaching out to us! I’m very sorry about this issue you are experiencing.
Can you please access your Dashboard and head over to Events-> Settings -> Community-> “Community rewrite slug” and check if the slug you have registered there is community?
If everything is correctly setup there, please head over to Settings -> Permalinks for a permalink flush (no need to change anything, just visit the permalinks page: WordPress will automatically flush your permalinks once you visit it).
I hope this helps. If you need anything else in the meantime, please let me know and I’ll be happy to assist!
Regards,
Patricia
