error when using it

There is an error but i gave it 5 stars because after fixing it the plugin would be the best…

the error is that it gives me this message in any page i put the code of video gallery in, which is:

“Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback, non-static method bbp_5o1_toolbar_format::decode_magic_code_shortcode() should not be called statically in /home3/ihacomp/public_html/denteach.com/wp-includes/plugin.php on line 213”

and below it the video gallery working just fine, but the text of error looks ugly and it refers for a bug, the site working fine when i remove the code of video gallery from the page..
