Syntax error on line 29 of /etc/apache2/sites-enabled/website-name-le-ssl.conf: Could not open configuration file /etc/letsencrypt/options-ssl-apache.conf: Permission denied
I don’t know how this got into this condition, but you can probably fix this problem with
sudo chmod o+x /etc/letsencrypt
That should allow processes not running as user root or group root to access files and directories within /etc/letsencrypt if they know those files’ or directories’ names already and they have permissions to access the individual files or directories.
