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');

2. 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>

3. Database Connection Error

If WordPress cannot connect to the database, a database connection error will occur.

define('DB_HOST', 'localhost');
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');
