I've made a Facebook app to implement fecebook login on my php Saas solution.
I can't add a domain in the settings->advanced section.
A dialog is shown. I write the domain and click the [add] button. Now a spinner is showing and just keeps spinning. I've tried everal computers and mobile devices. It is the same everywhere.
What do I do wrong?
I have set the domains in then settings -> basic sections and I have added all the url callbacks.
image af dialog with spinning button - with protocol
EDIT: It is the same thing with or without protocol. The placeholder in the field states to enter an URL but either with or without the protocol part nothing happens.
