Even though WordPress is one of the largest content management systems online, there can still be errors. When these errors come up, the good thing is, there are plenty of places to find the information needed to fix common WordPress errors.

Before you try to fix any error, make sure you fully back up your WordPress website. This will ensure you have everything you need before you try to fix the error.
<h2>404 Post Error</h2>
WordPress will sometimes show a 404 error page when somebody tries to access one of your posts. When this happens, you need to know how to repair the error. Typically, this error means you have an issue with your permalink settings. Make sure to check the permalinks first before trying anything else. If this isn't the issue, you may need to update your rewrite rules.

<h2>Memory Exhausted Error</h2>
Sometimes, the memory WordPress uses runs out. This may happen when you install a plugin and it's too big for the site or you have too much content/images taking up space. The error looks like this:

This error can be fixed in the wp-config.php file. You can find this fie in the root WordPress directory and on the first line, you will see define('WP_MEMORY_LIMIT', '64M'). If it doesn't say 64M, you will need to change this line of code to reflect this size.
<h2>Locked Out of WordPress Admin</h2>
Maybe you've found yourself locked out of the WordPress admin area. This happens when you forget your password and you cannot access your email to recover it. Sometimes, this happens due to a plugin error or a hacker. If this happens, you will need to know how to fix it.

You can fix this error by access the phpMyAdmin area in your cPanel. If you know the database you're using for the site, just access it and go to the wp_users section. Here, you can change the password and the email for accessing your lost password.
<h2>Still Down for Maintenance Error</h2>

If you update WordPress, a plugin or your theme, you may end up stuck in maintenance mode. This can be very annoying, but it's very easy to fix. Usually, this error happens when an interruption happens and you don't let the update complete.

The easiest way to fix this error is to access your root WordPress folder. You will need to make sure the hidden files are showing (This varies from one host to another, but is typically a check box in the file manager area.). Now, just find the .maintenance file and delete it. This is a temporary file that puts you in maintenance mode.
<h2>WordPress Syntax Error</h2>
If you try to add code snippets in WordPress, you may get a syntax error. This means, you either missed something or the code isn't written properly. Typically, you can fix this error by fixing the last snippet of code you were editing.
<h2>WordPress Internal Server Error</h2>

You may run into the "500 Internal Server Error" or just a regular "Internal Server Error." This common error is one of the harder ones to fix. The problem is, the error doesn't tell you where to look. Here are a few potential solutions to try first.
<ul>
	<li>Corrupt .htaccess file</li>
	<li>PHP Memory Limit Needs Increased</li>
	<li>Plugin Issues</li>
	<li>Core Files need Re-uploaded</li>
</ul>
Sometimes, if you delete all your plugins and install them one by one, you can find the issue. Other times, you will need to contact your hosting support.
<h2>Sidebar Displaying Below Content Error</h2>
A common issue beginners encounter is the sidebar they create displaying below the content on the page. This happens often when you're working with the code snippets on your site. Sometimes it can be a CSS issue and it can be as simple as changing the size of the content area. However, other times, it can be a bit more difficult. Check the code you were last updating for the issue before doing anything else.

These are just a few of the most common errors found in WordPress. Many beginners don't know how to fix these errors, but now, you can handle most of them without needing to contact the support of your hosting company.
