I was just setting up a ssl certificate but just entered 1 character for each field. There was no error message in ispconfig (i.e. user thinks ssl creation was a success), but the ssl keys weren't created and there is an error in the log: # tail /var/log/ispconfig/cron.log 0421:error:0D07A098:asn1 encoding routines:ASN1_mbstring_ncopy:string too short:a_mbstr.c:147:minsize=2 chmod: cannot access `/var/www/clients/client0/web7/ssl/www.example.com.key': No such file or directory
