How to Fix Page Not Found Errors by Flushing Permalinks
The Page Not Found Error
If you're getting a Page Not Found (404 error) while using SportsPress or any other WordPress plugin, here's a quick fix that might solve the issue.
We'll go into the dashboard then hover over Settings and click Permalinks. We should make sure that something other than Default is selected. "Day and name" is generally a safe choice. Now we can flush the permalinks by clicking Save Changes.
If we go back to the page and refresh, the content should be displaying properly now. If you're still having issue, try changing the SportsPress URLs.
