Sites -> Domain -> SSL -> SSL OFF Sites -> Doiman -> SSL -> SSL Action -> Delete certificate but - certificates still exist in /var/www/site/ssl - SSL KEY and SSL Bundle are still populated SSH, navigate to SSL folder, delete all files. so /var/www/site/ssl folder is empty Restart Apache, restart browser. But for this site there are SSL KEY and SSL Bundle are still populated... Any idea where is this data coming from ? ISPCONFIG version 3.1.15.p2 The problem originates from inability to enter new (renewed) certificates. In the meantime I enabled Let's Encrypt, which is working normally. But these two fields are stil populated... Any idea is appreciated.
