What a 500 Error Means
Work the fixes in likelihood order:
- Rename .htaccess — File Manager (hidden files shown): rename public_html/.htaccess to .htaccess.old; site returns? Regenerate permalinks to write a fresh one.
- Test plugins — rename wp-content/plugins to plugins.old; if the site returns, rename back and deactivate plugins one by one to find the offender.
- Theme check — same trick with the active theme folder, or switch to a default theme via the database.
- Raise PHP memory — wp-config.php:
define('WP_MEMORY_LIMIT', '256M');or the MultiPHP INI Editor. - Read error_log — cPanel → Metrics → Errors shows the real cause; stop guessing from there.
Each fix is minutes and reversible. The log-reading habit is the permanent one — the PHP error logs guide covers where the files live, and sibling errors in the 503 fix guide.
Fix 1: Corrupt .htaccess File
The questions below cover what the fixes above assume: what a 500 actually means versus a 404 or 503, what typically causes it on WordPress specifically, why sites break right after a plugin update, how to raise the PHP memory limit safely, where the error log lives in cPanel, and whether the host is ever the culprit. Each answer names the exact file, panel path or command — the same checklist support engineers run — so most 500s end without a ticket.
Fix 2: Plugin or Theme Conflict
Update plugins and themes on a copy or straight after a backup, one at a time if the site is a shop. A white screen after an update is usually one plugin: rename its folder via the file manager to disable it. Remove plugins you do not use — they are unpatched code.
Fix 3: PHP Memory Limit
Pick the newest PHP version the site's plugins actually support, set it in the panel, and load the homepage plus one form. If the site whitescreens, switch back and read the error log before you try random plugins. Do not leave a shop on a PHP release that no longer gets security fixes.
Fix 4: Core Files and PHP Version
Pick the newest PHP version the site's plugins actually support, set it in the panel, and load the homepage plus one form. If the site whitescreens, switch back and read the error log before you try random plugins. Do not leave a shop on a PHP release that no longer gets security fixes.
Reading error_log for the Real Cause
On WordPress core reinstallation, the honest summary is that defaults matter more than brand names — a well-set budget plan outranks a mis-tuned premium one. WebJi® documents its defaults openly and adjusts them per ticket when workloads need it.
