I am getting :
[error] 13148#0: *59843 FastCGI sent in stderr: "PHP message: PHP Warning: mysql_query(): Access denied for user ''@'localhost' (using password: NO) in /path/wp-content/plugins/contus-video-gallery/front/views/videoshortcode.php on line 587
But this happens only when retriving and loading video details.
I could able to see the videos for each category in admin page.
I have checked the db details in wp-config, seems fine.
Thanks for any help in advance.
