Fixes for the errors that take a WordPress site down.
Troubleshooting
Broken images have four possible causes: the file is gone, the URL is wrong, the server refuses to serve it, or a plugin rewrote the path. Test the image URL directly to find out which.
Troubleshooting
Separate a form that never submits from a form that submits and loses the notification, then fix the layer that is actually failing in Contact Form 7, Elementor, WPForms or Ninja Forms.
Troubleshooting
WordPress sends mail through PHP by default, and most hosts and inboxes reject it. Find out whether the message left the server, then move the site to authenticated SMTP.
WooCommerce
Fix checkout spinning, reloading or rejecting orders by identifying whether validation, JavaScript, payment webhooks, sessions, caching or a plugin conflict failed.
Elementor
Diagnose an Elementor editor stuck on a gray screen or spinner by checking console and PHP errors, Safe Mode, plugin conflicts, memory, URLs and proxy settings.
Troubleshooting
First confirm WordPress saved the revision, then identify whether the stale version comes from browser, plugin, host, CDN, generated CSS or the wrong environment.
Troubleshooting
Log WordPress PHP errors without showing them to visitors, reproduce the problem once, read the relevant entries and disable or secure logging afterward.
Troubleshooting
Disable one broken plugin by renaming its folder, deactivate all plugins through WP-CLI, or reset the plugins directory safely without deleting settings.
Troubleshooting
Fix wp-admin returning to the login form by clearing site cookies, matching WordPress URLs and HTTPS, bypassing cache, and isolating authentication plugins.
Troubleshooting
Raise WordPress memory in wp-config.php, verify the effective PHP limit, and use the fatal error log to find the plugin, query or import that exhausted it.
Troubleshooting
If the error appears during a theme or plugin upload, check PHP upload limits. If it appears after an admin action, refresh the nonce and investigate caching, cookies or time drift.
Troubleshooting
Fix the right layer: resave rewrite rules when all pretty permalinks fail, repair one page’s slug or status when only one URL fails, and add redirects for moved content.
