Let’s take a look at how to solve the most common WordPress errors (one by one).
1. How to Fix Internal Server Error
Perhaps the most confusing WordPress error that a beginner may come across is “Internal Server Error”, or sometimes “500 Internal Server Error”.
This error usually appears when there is something wrong, but the server is unable to identify where the problem is. Since the error message does not indicate where you should look for the error, it is pretty much up to you to figure this out.
We have compiled a list of solutions that you can try and one of them will help you resolve it. [Fix internal server error]
2. How to Fix Syntax Error in WordPress
This error usually occurs when you are trying to add code snippets into WordPress and have accidentally missed something or the code has incorrect syntax. This will result into a PHP parse error and you will see a notice like:
Parse error- syntax error, unexpected $end in /public_html/site1/wp-content/themes/my-theme/functions.php on line 278The error message would indicate the unexpected thing found in the code and the location of the script where the error occurred with line number. To fix this issue you will have to correct the syntax. Most of the time it is a missing bracket, or some unexpected character in the code. [Fix syntax error in WordPress]
3. How to Fix the Error Establishing a Database Connection in WordPress
This error message is clear that your website is unable to connect to the database. However solving this error can be tricky for beginners.
Usually this occurs when a user has entered or modified their database credentials (database host, database username, and database password) incorrectly. Sometimes your database server could be unresponsive, or your database may have corrupted.
However, mostly it is incorrect database login credentials. Take a look at common solutions for this problem. [Fix error establishing database connection in WordPress]
4. How to Fix the WordPress White Screen of Death
This error usually results into a plain white screen with no error message. This makes it the most puzzling because you have no clue where to look and what to fix.
Most of the time it is caused when a script exhausts PHP memory limit. It can also happen due to a configuration on the server. It is also possible that a user would only see white screen of death on certain sections of their site. [See how to fix WordPress white screen of death]
5. How to Fix WordPress Posts Returning 404 Error
The symptoms of this error is that when a user visits a single post on their site they get a 404 page – not found error.
The user can browse all other sections of their site including the admin area. The most common cause of this issue is permalink settings in WordPress. To solve this issue a user would need to reconfigure their permalinks settings or manually update their rewrite rules. [Fix WordPress posts returning 404 error]
6. How to Fix the Sidebar Below Content Error in WordPress
Another common issue beginners face is when the sidebar appears below the content when it is supposed to appear next to the content. This issue is mostly caused by WordPress themes.
Sometimes when users are adding code snippets to their site, they may accidentally forget to close an html div tag or add an extra closing div which may result into breaking the theme layout. Another common cause is using disproportionate width in CSS or not clearing float properly. [Fix sidebar appearing below content error in WordPress]
7. How to Fix White Text and Missing Buttons in WordPress Visual Editor
Sometimes buttons from WordPress visual editor may disappear or start showing blank white spaces instead of buttons.
This problem may occur when concatenated JavaScript is not working. It may also caused by missing or corrupt TinyMCE files, or conflict with some other plugin that modifies or extends the TinyMCE shipped with WordPress. [Fix white text and missing buttons in WordPress visual editor]
8. Fix: WordPress Memory Exhausted Error – Increase PHP Memory
Indications of this error could be a white screen of death, or an error message like this one:

[Fix WordPress memory exhausted error]
9. What To Do When You Are Locked Out of WordPress Admin (wp-admin)
Sometimes you may find yourself locked out of the WordPress admin area. This could happen if you forgot your password and don’t have to access to password recovery email.
A plugin or code that incorrectly tries to make some changes into admin section can also lock you out. You may also lose access to admin area due to a hacked WordPress site. [Fix locked out of WordPress admin issue]
10. How to Fix WordPress Login Page Refreshing and Redirecting Issue
Symptoms of this issue are that when a user attempts to login to the WordPress dashboard, they are redirected by WordPress back to the login page.

11. How to Fix Image Upload Issue in WordPress
Sometimes a user would suddenly notice that all the images from their site are gone and are showing broken image placeholders. When the user tries to upload an image to a post using the media uploader, it results into an error.

12. How to Fix Common Image Issues in WordPress
Uploading images to a WordPress site can be confusing for someone new to WordPress. A user may be unable to find out how to align images, resize or crop them, or display them in a gallery format.

If for some reason the update is interrupted, then WordPress does not get the chance to put your site out of the maintenance mode. This error would lock down your entire site and make it unavailable for admins as well as visitors. [Fix briefly unavailable for scheduled maintenance error]
15. How to Fix WordPress Not Sending Email Issue
The most common symptom of this problem is not receiving any contact form or WordPress notification emails from your site.

16. How to Fix WordPress RSS Feed Errors
Most WordPress RSS feed errors are caused by poor formatting. You may see errors like these:
XML Parsing Error: XML or text declaration not at start of entity
Location: http://example.com/feed
Line Number 2, Column 1:Depending on what browser you are using, your RSS feed error message may vary. You can also see this error message when visiting your feed in a browser.

17. How to Fix 403 Forbidden Error in WordPress
403 Forbidden error code is shown when your server permissions don’t allow access to a specific page. This is why the error is usually accompanied by the text:
403 Forbidden – You don’t have permission to access ‘/’ on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.There are different scenarios when you can see this error. Incorrect file permissions, poorly coded security plugins, or server configuration are the most common culprits. [Fix 403 Forbidden error in WordPress]
18. How to Fix Error Too Many Redirects Issue in WordPress
This error usually occurs due to a misconfigured redirection issue. As you know that WordPress has SEO friendly URL Structure which uses the redirect function. Several other popular WordPress plugins also use the redirect functionality as well.
Due to a misconfiguration in any of these redirection tools, your site may end up redirecting users to a URL that is actually redirecting them back to the referring URL. In that case the user’s browser is trapped between two pages causing a redirect loop. [Fix too many redirects issue in WordPress]
19. How to Fix “Upload: Failed to Write File to Disk” Error in WordPress
This error can occur due to a number of reasons. However, the most common one is incorrect folder permissions.
Each file and folder on your website has a set of permissions. Your web server controls access to the files based on these permissions. Incorrect permissions to a folder can take away your ability to write files on server. This means your web server cannot create or add new files to that particular folder. [Fix Upload: Failed to write file to disk error]
20. How to Fix “This site ahead contains harmful programs” Error in WordPress
Google marks a website with this warning if they find any suspicious code that could be a malware or trojan. Sometimes the reason for this is that your website is hacked and is now used to distribute malicious code.

22. How to Fix Fatal Error: Maximum Execution Time Exceeded in WordPress
WordPress is coded mainly in PHP programming language. To protect web servers from abuse, there is a time limit set for how long a PHP script can run.
Some WordPress hosting providers have set this value to a higher level while others may have set it to a lower level. When a script reaches the maximum execution time limit, it results into maximum execution time exceeded error. [Fix maximum execution time exceeded error in WordPress]
