Troubleshooting

Start from the symptom you're seeing - each guide walks through the likely causes and fixes. The reusable procedures those guides rely on are grouped under Common fixes.

In this section

• Site is down or inaccessible - work out whether the site is really down, and why
• Site is slow - find what's slowing the site down and speed it up
• Site shows an error - diagnose a white screen or 500 error
• Site times out - track down 502 and 504 timeout errors
• Changes don't show up - clear the browser, server, and CDN caches
• Can't log in to WP Admin - fix password and cookie login problems
• Too many redirects - break a redirect loop
• Stuck in maintenance mode - fix the WordPress maintenance mode bug
• Hacked or infected website - spot the signs of an infected site and see how we clean it

Common fixes

• Deactivate plugins and themes - isolate an issue by deactivating plugins and switching themes
• Enable WordPress debugging - surface PHP errors with WP_DEBUG
• Clear your browser cache and cookies - hard-refresh, clear caches, and cache-bust assets
