When using BasePress knowledge base you may encounter some errors for different reasons, let’s see how to fix common 404 errors:

1. You haven’t selected the main page containing the shortcode in the General settings.
2. You haven’t created any Knowledge Base yet. Even if you use it as ‘Single Knowledge Base mode’ you still need to create a Knowledge Base to function. Only the name is necessary in this case.
3. You haven’t created any section yet.
4. You haven’t selected any Knowledge Base or section for the articles.
5. You have changed the slug of the page with the shortcode. In this case just go to BasePress Settings and just click ‘Save Settings’.
6. You have changed the slug of a Knowledge Base. As above just go to BasePress Settings and just click ‘Save Settings’.
