If you remove/comment out that line Coppermine works as expected?
If so, please add the following code to your theme's theme.php file:
/******************************************************************************
** Section <<<pagefooter>>> - START
******************************************************************************/
// Function for writing a pagefooter
function pagefooter()
{
/*
//global $HTTP_GET_VARS, $HTTP_POST_VARS, $HTTP_SERVER_VARS;
global $USER, $USER_DATA, $CONFIG, $time_start, $query_stats, $queries;
global $template_footer;
$custom_footer = cpg_get_custom_include($CONFIG['custom_footer_path']);
if ($CONFIG['debug_mode']==1 || ($CONFIG['debug_mode']==2 && GALLERY_ADMIN_MODE)) {
cpg_debug_output();
}
$template_vars = array(
'{GAL_NAME}' => $CONFIG['gallery_name'],
'{GAL_DESCRIPTION}' => $CONFIG['gallery_description'],
'{SYS_MENU}' => theme_main_menu('sys_menu'),
'{SUB_MENU}' => theme_main_menu('sub_menu'),
'{ADMIN_MENU}' => theme_admin_mode_menu(),
'{CUSTOM_HEADER}' => $custom_header,
'{JAVASCRIPT}' => theme_javascript_head(),
'{CUSTOM_FOOTER}' => $custom_footer,
'{VANITY}' => (defined('THEME_IS_XHTML10_TRANSITIONAL')) ? theme_vanity() : '',
'{CREDITS}' => theme_credits(),
);
echo template_eval($template_footer, $template_vars);
*/
}
/******************************************************************************
** Section <<<pagefooter>>> - END
******************************************************************************/
That's not the final solution, but it should fix your whole gallery if pagefooter is really the cause. Obviously it currently won't display the footer, as I commented out the whole content. Please report if it works as expected.
