I just finished migrating my server, and was unable to write/make updates on my Wordpress server. I ended up following a guide and ran these permission changes: sudo usermod -aG www-data $USER sudo chown -R www-data:www-data /var/www sudo chmod -R 774 /var/www This fixed the write issues, but I am no longer able to access the ISPConfig Login page. Any help is super appreciated! Thank you!!
