Hello,
Thanks for the plugin. you did a great job.
I want to mention this problem that I have and hope you can easely solve this.
I receive this warning message: Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'wpdm_popup_link' not found or invalid function name in /home/theworld/public_html/www.gravenberchconsulting.com/wp-includes/plugin.php on line 505
Can you advise how to act on this.
