Hi,
from this error seems that you have not specified the correct domain in your Facebook app, but from your screenshot the field App Domain seems valid.

This seems a facebook problem, can you please try by creating another app?

Hi,

I have created another app but still it is not working. Here are print screens.

Looking forward to your help.

Regards
Wilfred

Hi,
after some investigation seems that Facebook allow login only from HTTPS sites, this is something that has been added recently.

Have you filled also Redirect URIs in according with all App domains (see screenshot)?

Hi,
Can you please post me screenshot from Facebook Login->Settings (like screenshot in my previous reply) ?

Hi,
missing urls at "Valid Oauth Redirect URIs", see step 4 at http://docs.easy-profile.com/index.php/article/social-connect-facebook

Hi,
Facebook have made many updates in the last year, now in the new Apps it requires "Valid Oauth Redirect URIs" (this was added 6 months ago) and Https (this is something of very new, so our docs does not contain any reference, we will update soon)

before update easy-profile

This is not something that regards Easy Profile updates.

the installation on another website we have still works

This happen because your Facebook apps on this site is a old version (so not require something like https) but it is not yet deprecated (so it works)

Can you please send me the screenshots of your new Facebook App configuration?
