Sometimes, when you make changes to a widget or to a post, your WordPress website won't update immediately. This can make it hard to see the changes you've made and make sure they are done correctly. Here's what you should do if this happens to your WordPress website.
<h2>Most Common Symptoms</h2>
The one thing you will notice before any other, when your site won't update immediately, is new posts not showing up on the homepage. You can still see the post in the single post view, but for some reason it won't show up on your actually homepage.

You may also notice that changes you make to a widget don't update very quickly. This is another issue you will notice on your homepage first.
<h2>What Causes this Issue?</h2>
Often, when WordPress users experience one or both of these symptoms it's due to the browser cache. This is especially true with Google Chrome, which will show you a cached copy of your website instead of the updated version.

If you want to remedy this issue, just click CTRL + F5 or for MAC users Cmd + R. This will reload the page and allow the new version to show up.

Another common issue you may be experiences is a bad configuration of the cache plugin you're using for WordPress. Start by emptying all caches with your plugin and see if this solves the issues. You can do this from the settings page. Here's what it looks like for the <a href="https://wordpress.org/plugins/w3-total-cache/">W3 Total Cache WordPress plugin</a>.

Most of the time, you will get a button similar to this one to click and empty the cache. Sometimes it will say "empty all caches."

After you've emptied the cache, you should look at the settings under "Page Cache."

If you find that the option called, "Don't cache front page" isn't selected, you may have found your issue. Make sure this is selected and update your website.

If none of these options fix your issue, you may want to deactivate the cache plugin from the plugin menu. Then, you will want to see if this fixes the issue. If it does, you may want to switch to a different caching plugin, such as <a href="https://wordpress.org/plugins/wp-super-cache/">WP Super Cache</a>.
