Mao,

You told me:
"It's showing the Feed Title and Description but for the rest it's giving the message

"<an error occurred while processing this directive> <an error occurred while processing this directive>" "

This indicates two of the three SSI tags were working...However, this isn't the case, so I've spent an hour trouble shooting with incorrect info.

You haven't installed the random script correctly. Go back and check the path to perl, permissions, upload in ascii, etc.

I'm going to bed...
