In functions.php add the red parts
// This adds arbitrary content at various places in the center (= content) column:
function bfa_center_content($center_content) {
global $bfa_ata;
// PHP
// not for WPMU
# if ( !file_exists(ABSPATH."/wpmu-settings.php") ) {
if ( strpos($center_content,'<?php ') !== FALSE ) {
ob_start();
eval('?>'.$center_content);
$center_content = ob_get_contents();
ob_end_clean();
}
# }
echo $center_content;
}
I had disabled this for WPMU and not thought about what would be there instead then. I am just enabling it again I think for the next version. The plan was to add the option to dumb down Atahualpa for WPMU installs so PHP cannot be used but I'll leave that for another version in the future
