I've updated to version 3.1.
In administration, I get this error:
There is no Customer Area page on your site. If you already have one, just visit the plugin settings to set it.
» If you have not yet created one, we can do it automatically: create this page now
» If you already have one, just visit the plugin settings to set it.
I have a Customer Area Page setted, with right shortocode, but I still display the error.
