Locked out of WordPress or seeing a white screen

Forgot your password? Use the "Lost your password?" link on yourdomain.com/wp-admin — it emails a reset link. No email arriving? Your mailbox may not be set up; check Email and your spam folder, or reset it another way below.

Reset via the database: open Dashboard → Hosting → Databases, launch phpMyAdmin, open the wp_users table, edit your user, and set user_pass using the MD5 function with your new password.

White screen of death / 500 error: it's almost always a bad plugin, theme, or the wrong PHP version. Fixes, in order:

• Rename the wp-content/plugins folder in Files to plugins-off — if the site returns, a plugin is the culprit; rename it back and disable plugins one by one.
• Switch to a default theme (rename your active theme folder).
• Try a different PHP version.

Fastest recovery of all: restore a backup from just before the problem.
