Hello, I just want to ask if somebody also have this Error message: `Exception: strpos(): Argument #1 ($haystack) must be of type string, null given in file '/var/www/nextcloud/apps/social/lib/WellKnown/WebfingerHandler.php' line 105` I use a apache server with enabled social app 0.5.0beta3 and NC25.0.2 In the social app I don’t get message that webfinger is not set properly. But in ‘security & setup warning’ on administration page I get the warning that webfinger is not set properly. And the above Exception is thrown when I use in browser: `https://myexample.com/.well-known/webfinger` When I use: `https://myexample.com/.well-known/webfinger?resource=acct:michael@example.com` the JSON data is shown. Does anybody have an example how it must look like? Here is my one: ```auto subject "michael@example.com" aliases 0 "https://example.com/nextcloud/index.php/apps/social@Michael" 1 "https://example.com/nextcloud/u/Michael" links 0 rel "self" type "application/activity+json" href "https://example.com/nextcloud/index.php/apps/social@Michael" 1 rel "http://webfinger.net/rel/profile-page" type "text/html" href "https://example.com/nextcloud/u/Michael" 2 rel "http://ostatus.org/schema/1.0/subscribe" template "https://example.com/nextcloud/apps/social/ostatus/follow/?uri={uri}" ``` ---
