My WordPress site shows an error or white screen Print

Work through these in order — they cover almost every case.

1. Read the real error. cPanel → File Manager → public_html/wp-config.php: set WP_DEBUG to true, reload, then set it back.
2. Disable plugins. Rename wp-content/plugins to plugins-off. If the site loads, a plugin is at fault; rename it back and disable plugins one by one.
3. Switch theme. Rename wp-content/themes/your-theme temporarily; WordPress falls back to a default theme.
4. Check limits. If PHP ran out of memory, raise WP_MEMORY_LIMIT in wp-config.php to 256M and confirm PHP 8.2 in cPanel → MultiPHP Manager.
5. Restore. Still stuck? Install a backup, or open a ticket with the exact error text and we will fix it.
