Thumbnail Images from Website Disappear After activating WPdiscuz

Hi,

I changed the location where wordpress stores images from the standard "wp-content-uploads'' to a custom IMG folder  editing wp-config.php and adding define( 'UPLOADS', ''.'img' );

When i activate WPdiscuz plugin, all thumbnails from my  website disappear. For some reason, WPdiscuz changes the behavior from the wp function "the_post_thumbnail".

Instead of returning the custom url where my images are stored, wp discuz interferes whith this function and changes the custom path ,where my images are, to the standard "wp-content-uploads", causing my thumbs to vanish as there is no image inside this folder. 

Example: correct path

 https://mysite.com/img/image.jpg 

is changed to the default incorrect one

https:// mysite.com/wp-content/uploads/image.jpg

How do I fix that as your comments plugin is the best in my opinion.  

Thanks.
