When in WordPress's DEBUG mode, the plugin produces errors because it calls wp_enqueue_script and wp_enqueue_style functions outside an init action. Please update it so that it calls the functions inside an init action hook function. It is annoying to have errors occupying a space on top of the page when I try to debug other errors. Thank you.
I am currectly patched the plugin myself but it would be really cumbersome when the time comes to update the plugin..
