8. Error Establishing Database Connection

8 Common WordPress Errors (And How to Fix Them)

The error establishing a connection to the database is very self-explanatory and reports that the connection to the database has been broken.

Causes of the database establishment error

Solution#1. Fix Problems With Your Hosting Server

It is a good idea to talk to your WordPress hosting provider about the problem.

Your hosting provider will be able to inform you if your database has been closed for exceeding your quota or if there is a problem with the server. If you are informed that everything is fine on the server, it is time to check your wp-config.php file.

Solution#2. Wp-config.php File Error

Open your wp-config.php file using FTP or file manager. Now verify that the database name, host, username, and password are correct. If you find any changes to these details, please correct them immediately. If you don’t know how to edit PHP files, it’s best to get familiar with the basics first.

Solution#3. Scan It To Check If It’s Been Hacked

WordPress is the most preferred open-source platform, but it is extremely vulnerable to security threats. So it’s no wonder that WordPress is the main target of hackers.

Use a security tool to fully scan your website and see if it is compromised. If you discover that your site has been hacked, don’t panic. Change your login details immediately and restore your site from backup.

7. White Screen of Death

8 Common WordPress Errors (And How to Fix Them)

This error usually causes a blank screen with no error message, which makes it more frustrating for you as you have no idea what to look for and what to fix.

Causes:

  • Often caused by the insufficient memory limit
  • Badly coded theme or plugin

Solution#1. Increase The Memory Limit

Since insufficient memory limit is a common reason for this error, it is recommended to increase the memory limit. To increase the limit, open your wp-config.php file and add the following line of code inside the main PHP tags.

define('WP_MEMORY_LIMIT', '64M');

The above code increases your memory limit to 64M.

Solution#2. Replace Your Theme With The Default Theme And Disable All Plugins

If the problem persists, disable all your plugins and replace the currently active theme with the default WordPress theme and check if it still shows a deadly white screen.

If the issue is resolved, your theme or one of its plugins is causing a blank screen. Activate one plugin at a time while monitoring the site. If this solves the problem, check your theme’s functions.php and remove any extra space at the bottom of the file.

6. 500 Internal Server Error

8 Common WordPress Errors (And How to Fix Them)

This is another common problem that almost every WordPress site encounters at least once. There are several potential causes.

Causes:

  • Exhausted PHP memory limit
  • Corrupted plugin functions
  • Corrupted theme functions
  • Corrupted .htaccess

Solution #1. Increase The Memory Limit

Follow the same steps to increase the memory limit as mentioned in the previous step.

Solution # 2. Edit The .htaccess File

Since the problem is usually caused by a corrupted .htaccess file, you will need to edit your .htaccess file. Open your .htaccess file in FTP or file manager and rename it with old .htaccess. Update your site and see if the problem persists. If this resolves the issue, click settings> permalinks and click save changes to reset .htaccess.

Solution#3. Deactivate All Plugins

If changing your .htaccess file had no impact on the problem, you may want to check your plugins. Disable all your plugins by clicking plugins? installed plugins.

Choose “disable” from the “bulk action” drop-down menu and click apply. It will automatically disable all your plugins. Now go to your website, update it, and check if the error is gone. In that case, activate your plugins one by one and see which plugin caused the problem.

Solution # 4. Replace The Wp-admin And Wp-includes Folders

If nothing worked, try replacing your wp-includes and wp-admin folders with fresh copies of a WordPress installation. Save and charge them. Refresh your browser and see if the problem is resolved.

5. Lost Admin Email and Password Retrieval is not Working

8 Common WordPress Errors (And How to Fix Them)

It’s common to forget your email or password, especially when you have a lot to remember. In this scenario, you probably clicked the lost password link to retrieve the details. But sadly, you never received the reset link in your inbox.

Cause:

The actual cause of this problem remains a mystery, but not the solution. There are certain things you can do to change your email and password without the need for a reset link.

Solution# 1. Edit Your Functions.php File

To make changes to a theme’s functions.php file, go to ../wp-content/themes/your_current_theme via FTP or file manager. Open your functions.php file and add the following line of code.

wp_set_password (“Desired new password”, 1);

Put the new password you want where it says “DesiredNewPassword”. Save the file and upload it again. After logging into your site, delete the code from the file and upload it again.

Solution# 2. Reset Your Email And Password Through phpMyAdmin

Login to your Cpanel. Click on phpMyAdmin and select your website database. Click on the wp_users table and edit your record. Enter a new value for user_pass. Remember that phpMyAdmin uses MD5 encryption, so you have to convert your password to MD5.

Choose the MD5 option from the drop-down menu under Features. Click save and update your website.

This error usually occurs when the website cannot find the page you specified.

Cause:

The permanent link setting is the main cause of the 404-page error.

2. Memory Exhausted Error

A memory exhausted error causes a deadly white screen or the following error

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 2348617 bytes) in /home/username/public_html/site1/wp-includes/plugin.php on line xxx

Cause:

The main cause is when a WordPress plugin or script runs out of the default memory limit.

Solution:

You need to increase your PHP memory limit. Although we mentioned all the steps to increase the memory limit in the first point, I am still writing here.

To increase the limit, open your wp-config.php file and add the following line of code inside the main PHP tags.

define (‘WP_MEMORY_LIMIT’, ’64M’);

The above code increases your memory limit to 64M.

Replace your theme with the default theme and disable all plugins
