Change 448 to $_SESSION[“language”] = “en”;
It works for me, but panel would be English only

Try running it all over again?

cp /usr/local/hestia/install/common/sudo/hestiaweb /etc/sudoers.d/
chown hestiaweb:hestiaweb /run/hestia-php.sock
chown -R hestiaweb:hestiaweb /usr/local/hestia/data/sessions

After running the first one, refreshing is effective.
