WP SMUSH PRO & WP DEFENDER Causing Image Uploading HTTP Error

Hi,

I have installed WP SMUSH PRO & WP DEFENDER PLUGIN on indorehd.com. But from few days I am getting http error while uploading any media items to my wordpress. When I deactivate both of the above plugins, it solves the problem. Please help me out with this as I want to use both these plugins on my site.

Awaiting Your Response,
Regards,
