Common WordPress Issues and How to Resolve Them by Optimum Presence Print

Introduction:

WordPress is a powerful and versatile platform for building websites. However, users may occasionally encounter issues that can impact the functionality and performance of their site. In this article by Optimum Presence, we'll discuss common WordPress issues and provide solutions to help you quickly resolve them.

1. White Screen of Death (WSoD)

The White Screen of Death (WSoD) is a blank, white screen that may appear when trying to access your WordPress site or dashboard. This issue is often caused by a PHP error, an exhausted memory limit, or a plugin/theme conflict.

Solutions:

• Increase PHP memory limit: Edit your wp-config.php file and add the following line: define('WP_MEMORY_LIMIT', '256M');.
• Disable plugins: Access your site's files using FTP or your hosting control panel's file manager and rename the "plugins" folder in the "wp-content" directory. If the issue resolves, rename the folder back to "plugins" and disable each plugin one by one to identify the problematic plugin.
• Switch to a default theme: Rename your current theme's folder in the "wp-content/themes" directory and WordPress will automatically revert to a default theme. If the issue resolves, the problem may lie with your current theme.

2. Error Establishing a Database Connection

This error occurs when WordPress is unable to connect to your site's database. Common causes include incorrect database credentials, a corrupted database, or issues with your web host.

Solutions:

• Check database credentials: Verify that your wp-config.php file contains the correct database name, username, and password.
• Repair the database: Add the following line to your wp-config.php file: define('WP_ALLOW_REPAIR', true);. Then, visit "yourdomain.com/wp-admin/maint/repair.php" and click "Repair Database."
• Contact your hosting provider: If the issue persists, reach out to your hosting provider for assistance, as the problem could be related to server issues or downtime.

3. 404 Not Found Error

A 404 error occurs when a requested page or resource cannot be found on your site. This may be caused by broken links, deleted content, or issues with your site's permalink structure.

Solutions:

• Update permalinks: Go to "Settings > Permalinks" in your WordPress dashboard and click "Save Changes" to reset your permalink structure.
• Check for broken links: Use a plugin like Broken Link Checker or an online tool like Dead Link Checker to identify and fix broken links on your site.
• Create redirects: If you've deleted or moved content, set up 301 redirects using a plugin like Redirection to direct users to the correct page or resource.

4. Internal Server Error (500)

An Internal Server Error (500) is a generic error message that can be triggered by various issues, such as a corrupted .htaccess file, PHP memory limit exhaustion, or problems with plugins/themes.

Solutions:

• Check the .htaccess file: Rename your site's .htaccess file and create a new one by visiting "Settings > Permalinks" in your WordPress dashboard and clicking "Save Changes."
• Increase PHP memory limit: Follow the steps mentioned in the WSoD section to increase your PHP memory limit.
• Troubleshoot plugins and themes: Follow the steps mentioned in the WSoD section to identify problematic plugins or themes.

5. Image Upload Issues

Issues with uploading images can arise from file permission errors, issues with the image library, or problems with the upload folder.

Solutions:

• Check file permissions: Using FTP or your hosting control panel's file manager, ensure that the "wp-content/uploads" folder has the correct permissions (755 or 775 for folders and 644 or 664 for files).
• Verify the image library: Ensure that your server has the necessary image libraries (GD Library or ImageMagick) installed and enabled. If not, contact your hosting provider for assistance.
• Define the upload path: In your wp-config.php file, add the following line with the correct path to your uploads folder: define('UPLOADS', 'wp-content/uploads');.

6. WordPress Stuck in Maintenance Mode

When updating plugins, themes, or the WordPress core, your site may temporarily go into maintenance mode, displaying a message like "Briefly unavailable for scheduled maintenance." If the update process is interrupted or encounters an error, your site may get stuck in maintenance mode.

Solution:

• Delete the .maintenance file: Access your site's root directory using FTP or your hosting control panel's file manager and delete the ".maintenance" file.

7. Login Page Refresh/Redirect Loop

Sometimes, when trying to access your WordPress admin area, you may encounter a login page refresh or redirect loop, preventing you from logging in. This issue can be caused by incorrect site URL settings, issues with the .htaccess file, or conflicts with plugins.

Solutions:

• Update site URLs: In your wp-config.php file, add the following lines with your correct site URLs: define('WP_HOME', 'https://yourdomain.com'); define('WP_SITEURL', 'https://yourdomain.com');.
• Check the .htaccess file: Follow the steps mentioned in the Internal Server Error section to check and reset your .htaccess file.
• Troubleshoot plugins: Follow the steps mentioned in the WSoD section to disable plugins and identify any problematic ones.
