Fatal error: Call to undefined function: bloginfo()

I’m trying to get coppermine to include my WordPress 1.5 header and footer files.

I think I got coppermine to recognize the header and footer files, but as it starts to read the files it causes these errors:

In the header.php file:

Fatal error: Call to undefined function: bloginfo() in /usr/local/psa/home/vhosts/rvadventure.ca/httpdocs
/wp-content/themes/lilbit/header.php on line 5

And in the footer.php file:

Fatal error: Call to undefined function: bloginfo() in /usr/local/psa/home/vhosts/rvadventure.ca/httpdocs
/wp-content/themes/lilbit/footer.php on line 4

What is bloginfo ?

Also, as a test, I removed line 5 from the header.php file and line 4 from the footer.php file, and the errors went away but my header and footer were not displayed – only the coppermine tables with the pictures appeared.

What am I doing something wrong ? Coppermine obviously sees the header and footer files but wont load them.
