WordPress error problems revealed: solutions revealed

WordPress is one of the most popular website building platforms in the world. However, it is inevitable to encounter various problems and errors during use. Sometimes, these problems may be caused by plugin conflicts, theme incompatibility, server configuration, etc. Today we will reveal some common WordPress errors and problems, provide solutions, and provide specific code examples to help you quickly solve WordPress error problems.

  1. White Screen of Death

The white screen problem is a common error in WordPress, which causes the website to fail to load properly. The user only sees a blank space. This can be caused by plugin conflicts, PHP errors, memory limitations, etc. Solutions include disabling plugins, increasing memory limits, debugging PHP code, etc. The following is a specific code example:

define('WP_DEBUG', true);
define('WP_MEMORY_LIMIT', '256M');
  1. 404 Page Not Found

When the page visited by the user does not exist , a 404 page will be displayed. But sometimes, even if the page exists, a 404 error will appear. This may be due to pseudo-static linking, incorrect htaccess file configuration, etc. Solutions include re-saving fixed links, modifying htaccess files, etc. Specific examples are as follows:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
  1. Database Connection Error

If WordPress cannot connect to the database, a database connection error will occur. This may be caused by incorrect database username and password, database server failure, etc. Solutions include checking wp-config.php file configuration, repairing the database, etc. The code example is as follows:

define('DB_NAME', 'database_name_here');
define('DB_USER', 'username_here');
define('DB_PASSWORD', 'password_here');
define('DB_HOST', 'localhost');
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');
  1. Memory Exhausted Error

Sometimes, WordPress consumes too much memory and causes Exhaustion error. This may be due to a plugin or theme taking up too much memory, or the server is not configured properly. Solutions include increasing memory limits, optimizing plug-ins, themes, etc. The code example is as follows:

define('WP_MEMORY_LIMIT', '256M');
  1. Security Vulnerabilities

Security issues in WordPress may cause the website to be hacked, data leaked, etc. Solutions include regularly updating WordPress, plugins and themes, installing security plugins, configuring security policies, etc. Specific code examples are as follows:

define('DISALLOW_FILE_EDIT', true);
define('FORCE_SSL_ADMIN', true);
