When troubleshooting issues with WordPress, there are a few basic steps you can take to identify and resolve common problems. Here's a list of troubleshooting techniques to help you get started:


1. Check for Plugin or Theme Conflicts

Deactivate all plugins and check if the issue persists. If it resolves the problem, reactivate the plugins one by one to identify the conflicting plugin. Switch to a default WordPress theme (e.g., Twenty Twenty-One) to see if the issue is theme-related.


2. Clear Caches

If you're using a caching plugin or server-level caching, clear the cache to ensure you're viewing the latest version of your site. Clear your browser cache to rule out any browser-related issues.


3. Review Error Messages:

Check the error logs on your server for any error messages or warnings related to WordPress. The logs can provide valuable information about the issue.


4. Verify File Permissions

Incorrect file permissions can cause issues. Ensure that files and directories have the correct permissions (typically 644 for files and 755 for directories).


5. Disable Customizations

If you've made any recent customizations to your theme or added custom code, revert those changes temporarily to check if they're causing the problem.


6. Debugging Mode

Enable WordPress debugging mode to display any PHP errors on your site. Add the following line to your wp-config.php file:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );

This will log errors to a debug.log file in the wp-content directory.


7. Test with a Default .htaccess File

Temporarily rename your existing .htaccess file to something like .htaccess_old and create a new default .htaccess file. Check if the issue persists.


8. Verify Database Integrity

Use the WordPress built-in database repair feature. Add the following line to your wp-config.php file:

define( 'WP_ALLOW_REPAIR', true );

Visit the following URL: http://yourdomain.com/wp-admin/maint/repair.php and follow the instructions.


9. Update WordPress, Themes, and Plugins

Ensure you're running the latest versions of WordPress, themes, and plugins, as outdated software can lead to compatibility issues.


10. Seek Community Support

Consult WordPress forums, support groups, or online communities to seek help from experienced users who may have encountered similar issues.
