My site is giving a ‘page not found’ error when I try to look at a course or a page displaying categories. At first it would happen at random intervals and I could fix it by going to the permalink page in the dashboard and saving twice.
Now, however, the page not found error is happening frequently. I have not made any site changes or updates to cause the issue.
Can you explain why the site keeps breaking and if there is a more permanent fix? Thanks.
