Why can't I see my fanpage when the package expires?

When your shop expires, Fchat will return the shop to the Free version.

With the Free version, you can only connect 2 fanpages. 

If your current number of fanpages is more than 2, those fanpages will be temporarily hidden without losing any previous data and customer information.

You need to renew/upgrade the Fchat package for those fanpages to be displayed and used.
