Let’s Discuss Some Common WordPress Errors and How to Fix
1. How to Fix Internal Server Error
One of the most common errors that new WordPress site owners run into is “Internal Server Error” or “500 Internal Server Error.”
This error message appears when something on your site is causing the WordPress server to crash.
It’s not uncommon for beginner WordPress users to think that their site is broken when in reality all that happened was that a simple change or addition caused a plugin to conflict with another.
When you see this error message, the first thing you should do is save the page.
We’ve put together a list of options for you to try, and maybe one of them will help you solve the problem. Learn how to fix a WordPress internal server error.
2. This Site is Experiencing Technical Difficulties
In a recent update to WordPress, developers have introduced a new security feature designed to protect users from accidentally causing damage to their websites.
When activated, WordPress displays a simple error message stating that “This site is experiencing technical difficulties”.
This prevents users from accidentally causing any damage to their websites, such as creating extra spaces between words.
If you’re using a theme or plugin that is not yet compatible with this feature, WordPress provides a list of compatible themes on their website.
WordPress then sends an email notification to your WordPress admin email address with all of the details. This email message includes a link to the backend, where you can try to fix the problem.
Any of the fatal problems listed in this article can cause this error message to appear. It’s more difficult to figure out what’s wrong if you don’t have access to the admin email or can’t get WordPress emails.
If you can’t get WordPress emails then see this guide on fixing the WordPress not sending email issue.
3. How to Fix Syntax Error in WordPress
When you’re writing in WordPress, you may find that you’ve made a mistake when writing your text.
However, this doesn’t mean that your sentence is completely ruined—you can sometimes fix the error by adding new text in the same place as the original text.
This is often referred to as “syntax highlighting,” and it can be used to draw attention to important information, to make the text more interesting, and more.
In the same way, you can also use syntax highlighting to fix a simple error in your text.
You must correct the syntax to resolve this problem. A missing bracket or an unexpected character in the code is the most common cause. Read this guide on how to fix syntax problems.
4. How to Fix the Error Establishing a Database Connection in WordPress
When you’re trying to get your WordPress website up and running, the last thing you want to see is the “Error Establishing a Database Connection” error message.

This is a pretty common error on WordPress websites, but the symptoms of this error are pretty obvious – when a user visits a single post on their site, they are met with a 404 page – not found error.

This is a pretty frustrating experience for users, which is why it’s important to diagnose and fix this error as soon as possible. Sometimes, this error is caused by a simple typo in the URL.
A user would have to change their permalink settings or manually update their rewrite rules to fix this problem. Learn how to fix 404 errors in WordPress posts.
7. How to Fix White Text and Missing Buttons in WordPress Visual Editor
The classic WordPress editor is the text-based editor that has been around since WordPress first launched.
It’s what you see when you click the “Visual” or “HTML” button at the top of the editor.
The classic editor is sometimes called the “code” editor because you can write your posts in a text-only format instead of using the visual editor. You can switch back and forth between the two editors whenever you want.
8. Fix: WordPress Memory Exhausted Error – Increase PHP Memory
A white screen of death or an error message like this could be indicators of this issue:

9. What To Do When You Are Locked Out of WordPress Admin (wp-admin)
When this happens, you’ll need to access the WordPress admin area in order to change your password or theme settings.
If you’re having trouble logging into the WordPress admin area, you may be locked out due to forgetting your password.
This can happen if you’ve forgotten your password but don’t have access to your password recovery email.
In this case, you’ll need to go back and retrieve the email that was sent to your email address when you set up your WordPress account.

The symptoms of this issue are that when a user attempts to upload an image to a post or page, they are shown a broken image placeholder.
This means that the image has been uploaded successfully, but cannot be seen on the site because it is being held for moderation, which is usually the case when an image has been uploaded by a third party instead of the user.
This problem could be caused by a variety of circumstances. Look at how to fix picture upload problems with WordPress.

This means that your web server won’t be able to create or add new files to that folder. How to Fix an Upload: Error: Failed to write file to disc.
18. How to Fix Fatal Error: Maximum Execution Time Exceeded in WordPress
WordPress is coded in the PHP programming language, so it is important to protect web servers from abusive behavior by setting a time limit on how long a given PHP script can run.
This prevents malicious users from executing PHP code that could infect a server or cause other unwanted behavior.
In some cases, however, WordPress may terminate an innocent PHP script before the time limit is reached.
This is known as a “fatal error”, and it typically occurs when you attempt to update a plugin or modify other WordPress core files.

SSL / HTTPS stands for Secure Sockets Layer and Transport Layer Security. It’s the second level of encryption used in web browsing.

If a server is pretending to be on HTTPS, and its certificate doesn’t match, your browser will show you a “Certificate Error” message.
See this tutorial on how to fix common SSL difficulties in WordPress for further information and other errors caused by SSL misconfiguration.
32. How to Fix File and Folder Permissions Error in WordPress
When you install WordPress onto a new web hosting account, the hosting company usually sets up WordPress so that it can access the files and folders on your website’s hosting account.
However, sometimes WordPress can encounter errors when it isn’t able to access the files and folders on your website’s hosting account.
This is especially common when you’re using a shared hosting account with another website.
The main reason for this is that shared hosting companies don’t typically grant WordPress access to the files and folders on your website’s hosting account unless you tell the hosting company that you’re using WordPress and that you need WordPress to be able to access the files and folders on your website’s hosting account.
See our article on how to fix file and folder permissions in WordPress for more information.
