Hey Barry,
Thank you for reaching out to us!
To get started, could you please access your Dashboard and 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)? Be sure to clear your site cache and browser cache after this change.
Does it help you to solve the problem? If the issue persists, please let me know and I’ll be happy to help you with the next steps!
Best Regards,
Patricia
