That's good to hear however in this last instance the SSL cert was created and managed entirely in ispconfig and not imported. Also, the issue in this recent case goes beyond just the cert itself as https requests to the site in question reached the apache test page instead due to the missing content that had to be included in the httpd.conf. We had to manually work around this.
Also, in other cases we created the cert in ispconfig and then replaced the files as described in the manual -- however in some cases apache would simply persistently serve the self signed cert used for ispconfig ui on port 8080 no matter what we did. In other cases this did not happen and all was well.
Would be great if some light could be shed on this.
