Marcus, because of changes on Facebook side we have completely refactor the Contact importer API and presently there is no necessity to use Secure Canvas URL. Just left this field empty.

OK so you say I juts need to update right! Is there any tutorial on how to set up a new contact importer????

Thanks for your help.

Marcus, the manual on how to configure Contact Importer plugin will be edited in nearest future.  In the meantime you can use the same manual but skip steps on Secure Canvas URL configuration.
Your Facebook App should look like the screenshot below, for instance:

You are awesome Taissa thanks so much

is it possible to bypass facebook https ??? :)

DeFender, as I said before,  you don't need to use the Secure Canvas URL link in your  Facebook APP configuration.  The Contact Importer plugin manual will be changed in the nearest future.
 If I misunderstood you, please provide me with the screenshots and more details on what you are asking about.
