been there man turn on logging to see the actual error. In wp-config.php, above teh line that says to stop editing, add define('WP_DEBUG', true);, define('WP_DEBUG_LOG', true); and define('WP_DEBUG_DISPLAY', false);. Reload teh site, then read wp-content/debug.log. the fatal error line names the file, which tells you which plugin or theme is responsible. fingers crossed 🤞

this vid explains it way better than me lol

    WordPress sent an email about a technical issue mentioning a plugin, but the recovery mode link just loops back to teh error ;) This started right after copynig staging to live. Im not a developer, but I can follow instructions. Please tell me I dont have to rebuild everything. Any help is very welocme, customers are already asking what happened.

    ok so with SSH and WP-CLI its quicker: wp plugin deactivate --all --skip-plugins --skip-themes to recover, then wp plugin activate name one at a time. wp plugin list shows versions sooo u can spot what updated recently. lmk how it goes

    oh ive been there lol to disable all plugins without the dashboard, rename wp-content/plugins to plugins-off over FTP or the hosts file manager... wordPress deactivates everything it cant find :D if the site comes back, rename the folder back and then rename individual plugin folders one by one to find the culrpit. hope that helps :)

    Id restore the last backup first and investigate on a staging copy :) For a business site, getting back online fast matters more than finding the cause live. idk maybe im wrong lol
