The single page is not working! What can I do?
If when you open a single page it returns a ‘Page Not Found’ error, it’s possible that the permalinks are not working well. Go on Settings > Permalinks and save the settings again, even without any changes. This will make the permalinks option update.
Another possible problem is conflict of slugs. If you have a page with the same ‘slug’ (permalink name) of the team showcase, the single pages might not work properly. You will have to change or the slug of the page/post or the slug of the team showcase entries, in the plugin page.
