On the first connection on ISPConfig admin with HTTPS, i've got this error on a fresh Ubuntu 8.04 i386 desktop AND a fresh ISPConfig install on an Ubuntu 8.04 server i386 :
same serial number as another one . Please get another one with a unique number (translated from french ...)
I've seen on the Net that i should delete some certificates in Firefox ... but which ones ?
In fact i can not delete certificates : they are "back" when i restart Firefox ...
Any idea ???
