I got this error:
Code:
Warning: include_once() [function.include-once]: Filename cannot be empty in /home/forum/public_html/import.php on line 339
Warning: include_once() [function.include]: Failed opening '' for inclusion (include_path='.:/usr/local/php/lib/php') in /home/forum/public_html/import.php on line 339
Fatal error: Call to undefined function get_contacts() in /home/forum/public_html/import.php on line 342
What does it means?
