(I searched the support boards but couldn't find an answer. I did uncover a thread from back in December but the solution was never posted.)

Here's my problem: I can post a link or modify a link as an administrator (in the control panel), but I get an internal server error when I try either one as an end user.

Any suggestions?

My error log says that the add.cgi script is being terminated due to premature ending of script headers.
