[PHP-DEV] Apache gdb backtrace... Help?? From: David N. Moreno (El Guapo) (dmoreno <email protected>)
Date: 04/11/00

Hello,

  I have a problem like the one listed in the FAQ with getting a "Document
contains no data" error....

  I only get this error when attempting to use the phpMyAdmin package to
manage some MySQL database on a linux server.

  We are Running redhat linux 6.0 and here is the resulting backtrace info
