Everytime I generate an order, it don't send to the "sucess" page, everytime I will direct to the cart. Then the admin will receive an order mail an the customer don't.

If I test to generate pdf in backend, I will get a blank page.

Every function work correctly if I unistall the extension.

That usually means you encountered a fatal error - your server's error log should have more information on this server 500 error.
