Hey. I am so sorry i gave you the wrong URL. The actual URL using managed WordPress is
http://mohsha91.dream.press
The URL on which you checked is on VPS. I had a query about why the plugin is not compatible with the managed WordPress hosting. Dream press is market leader and i have used it on many WordPress websites and the performance is very good. But on your theme, the core plugin is encountering many problems as stated by the Dreamhost team. For account details, you can check the private content area.
Kindly look into this domain with the above gives issues
