As Apache::DBI hasn't been tested with mod_perl 2.0 yet, you will need to: 1) make sure you are using the prefork MPM for Apache (as Stas said, Apache::DBI can only work with that one) 2) You will probably need to run mod_perl 2.0 in compat mode: put PerlModule Apache::compat in your httpd.conf, before loading other modules (like Apache::DBI). You will probably also want to see the 2.0 docs at http://perl.apache.org/release/docs/ Good luck! -- Per Einar Ellefsen [EMAIL PROTECTED]
