I get error WordPress 502 Bad Gateway after login to WordPress site.
I quickly found an error message in error log of webserver.
FastCGI sent in stderr: "PHP message: Chyba databáze WordPressu: Table 'database.wp_wfLiveTrafficHuman' doesn't exist.
But what does that error mean?
I have tried to find something via Google search but nothing useful. Therefore navigated into a folder containing plugins and tried to remove plugins. Let’s ignore add-ons like gutenberg or cloudflare…
Error says that something looks for table wp_wfLiveTrafficHuman. Let’s guess which add-on could track traffic – Wordfence?
After removing Wordfence plugin I can log in WordPress site again 🙂
