Here are the top ten WordPress mistakes and How to Enhance Them:

Top Ten Frequent WordPress Errors and How to ImproveThem:

1.    500 Internal Server Error:

This is one of the most complicated WordPress problems a newcomer may experience. This usually happens when something goes wrong but your server is unable to identify the problem.


  • The corrupted. htaccess file is the root cause.
  • PHP’s memory limit has been reached.
  • The themes and plugin functionalities are faulty.


  • If your htaccess file is corrupted, open it in a file manager or using FTP and rename it to old. Htaccess, reload the page to see if the error has been resolved. If that resolves the problem, save your changes and restart the htaccess.
  • Insufficient RAM on your server might potentially create internal server issues. Increase the RAM limit in the.php.ini file to address the problem.
  • Disable all themes and plugins before activating them one at a time to locate the wrong one.

2.   White Screen of Death (WSoD):  

One of the most frightening issues in WP is a blank display screen or a plain white screen with no indication of the error. WSoD might cause your entire website to go blank and display nothing.

Why it will be a main server issue?  This is because no message is displayed on your screen, and you have no idea what’s wrong with your site.


  • Themes that are faulty or badly coded
  • Plugin compatibility concerns
  • PHP programming errors
  • Memory limit reached


  • A broken theme could possibly be the culprit; it’s better to disable themes and utilize the default WordPress themes to see which one is causing the problem.
  • If a plugin is causing an issue, it is better to disable it and check for error resolution.
  • Find and correct errors in the PHP code.
  • By inserting the appropriate code and raising the memory of your site, you can increase the memory limit of the wp-config.php file.
  • Enable debug mode in WordPress by adding the following line of code to wp-config.php: define(‘WP_DEBUG,’ true); To begin debugging, change it from false to true and update the file on your server. This allows you to look for page problems and WSoD reasons.

3.   Error establishing database connection:


The term implies that the connection to the database has been severed, and WordPress is unable to connect to the site’s database. When your website is unable to connect to its database, this error occurs.

First and foremost, it might occur when there is a high volume of traffic. The server is unable to keep up and sends you an error.


  • Problems with the web host
  • Error in wp-config.php file (where the database is stored)
  • A hacked website.


  • Check with your hosting provider to see whether you have hit the maximum size of your database, as this might also result in an issue.
  • Access the wp-config.php file and double-check all the details such as database name, host, username, password, and so on. Please correct and double-check any spelling errors. Learn how to modify PHP files and make the required modifications.
  • Because WordPress CMS is the most popular platform, it attracts a large number of hacking attacks. Check to see if your website has been hacked. In the event of suspicion, it is recommended that you change your login credentials and reload your site from a backup.

4.   Syntax Error / Parsing Error:

WordPress Syntax Error is the next common problem that many website owners have, and it is related to code structures. This typical WordPress issue usually happens when there is a little but major fault in the site’s coding. Also having an unsuccessful addition of code snippets when some syntaxes are missed. If the PHP code contains a syntax problem, the PHP parser is unable to interpret, read, and function properly.

Fortunately, it’s a self-explanatory error that directs you to the source of the problem.


  • The error can be a missing comma, missing extra characters, missing semicolons, missing quotes, random strings or variables, etc.


  • To correct the code by opening the source file, go to the mentioned line.
  • Focus on the lines above for the missing operators, and correct whatever is wrong with your syntax.
  • In a middle move, split the long codes so that instead of focusing on the extended code, the parser can give a fixed-line number of the broken code, and the repair process can be simplified.
  • Avoid compound syntax constructs; instead, opt for distinct and colorful syntax coloring.
  • Make a backup of the previous work codes.

5.    Mixed content error:

This problem is caused by your WordPress site’s wrong HTTPS/SSL (Secure Socket Layers) settings. SSL certificates, such as those from DigiCert, GlobalSign, and Comodo, help to protect your website by encrypting it. Certain insecure content on these safe sites, however, can cause this error, which can have an impact on SEO rankings and user experience.


  • Despite having an SSL certificate, some scripts, movies, or photographs are not loaded via secure SSL, and some pages on the secure site are not yet secured (HTTP).
  • SSL configuration error


  • Install and activate the SSL Insecure Content Fixer plugin to resolve the Mixed Content problem.
  • Even the Ahrefs audit tool can help in detecting and eliminating all HTTP content, hence fixing the issue.

6. You can’t connect to the administration

It’s usual to forget your email or password, especially if you have a lot of them. In this case, you most likely clicked on the lost password link to recover the information. However, you never received the reset link in your inbox.

Don’t be worried; it’s not a technological problem. This occurs when you forget your WordPress email address or password.


  • This error is caused by a lost or unrecoverable password.
  • The exact cause of this problem is unknown, but the cure is not. Certain actions can be taken to change your email and password without requiring the reset link.


  • Enter the code wp_set_password(‘DesiredNewPassword,’ 1) in the functions.php file, and then type your new password in the DesiredNew Password box. Save and upload the file.
  • To change your email and password, go to Cpanel > phpMyAdmin. Select a database for the website. Click the Browse link in the wp_users table.
  • Click Edit, and then enter a new password for user_pass using MD5 encryption, as phpMyAdmin does.
  • Choose the MD5 option from the “Features dropdown menu save,” then refresh your site.

7.   HTTP Image Upload Errors in WordPress

While uploading an image to the WordPress media library, an unexpected HTTP upload error occasionally occurs. We all like to add lovely images to our blogs for decoration. Your website has been operating nicely up to this point. However, your images are now giving you problems. The following are some of the causes and solutions to those problems:


  • Can cause most likely incorrect file permissions.
  • A web hosting or hack of your website.
  • Also, the plugin errors


  • Open the uploads folder on your site using SFTP to solve the issue.
  • Open the file permissions settings, and change the numerical value to 755 to enable the reading and writing of uploaded files.
  • If you attempt to upload images that are larger than the maximum image dimension, an image upload error can occur.
  • The picture dimensions should be maximized in accordance with WordPress’s recommendations.
  • To achieve this, go to Settings > Media, where you can see the large-sized media’s dimensions in pixels.
  • Also, you can upload the image into WordPress, by resizing it with a free program like Paint for Windows or Paintbrush for Mac.

8.  Allowed memory size exhausted

The PHP programming language, which is installed on your hosting server and operates in the background, is used to create WordPress. WordPress needs a minimum of 64 MB of PHP RAM to run efficiently. You might occasionally encounter the following fatal error when WordPress’ memory drops below 64 MB:


  • The primary reason is that WordPress plugin and scripts use up all of the allotted memory.


  • You must increase the PHP memory allotment.
  • Open your wp-config.php file, and then add the following line of code inside the primary PHP tags to raise the limit.

9.   Unavailable due to scheduled maintenance error:

This error pops up when any update related to the plugin or theme is in the process; the site does not complete the update, and your site will remain in maintenance mode.

WordPress created a temporary “maintenance” file in the website’s root folder, which shows the maintenance error.


  • Unfinished or interrupted WordPress updates.
  • When WordPress updates a plugin or theme, it puts your website in maintenance mode. If the update is interrupted, it keeps your site in maintenance mode.


  • Access your root folder via FTP and delete the “.maintenance” file.
  • Manually complete the unfinished update.

10. Connection timed out

This error happens when your website attempts to load but it fails. What causes this to happen?

This is Because it necessitates an excessive amount of server resources, particularly on sites lodged on shared servers (many sites share the same bandwidth on the same server).

When a server is overloaded, it has problems loading the site. This issue is more common on shared hosting, which hosts multiple websites on a single server. Your server is unable to handle your site due to memory limits.


  • Exhaustive PHP memory limit is one of the causes.
  • Plugins in abundance
  • Theme function flaws


  • Increase the size of your PHP memory limit.
  • Deactivate plugins and themes one at a time to find the broken ones.
  • Increase your hosting plan’s server resources to avoid slowdowns and downtime.
  • Improve site speed by avoiding the use of heavy plugins and themes for bug fixes.
