You may have experienced error 404 before. In some cases, your main page is still accessible. Even when you check ID number, everything is working perfectly. This error may come back to caching rules.
There are unique rules for the cache. When these rules aren’t updated, these issues could occur. In fact, the main problem is with the permalinks. These links are designed for better readability. Although sometimes they can cause problems.
But you don’t need to worry about it. This issue is simply fixed when you flush permalinks. There are many ways to fix this issue. However, it all depends on your accessibility to WordPress and backend.
What Are Permalinks and How Do You Flush Them?
One of the built-in features in WordPress is the ability to use permalinks to increase the readability of your URLs. By default, after changing permalinks, WordPress deletes your cache.
As mentioned above by resetting your permalinks you can keep your cache rules updated.
