7.1. PGP encryption -- Server Error

As always, check the error log. The most common problem is something like:

   akopia.com 3Ex5lvta:akopia.com - [01/Sep/1997:09:08:43] simple /cgi-bin/simple
   > Encryption error:

Also, check the ScratchDir (usually tmp/) for .err files; they will contain PGP or GPG's error output.

Probable causes:

Interchange user ID doesn't have keyring

EncryptProgram directive set wrong
