• we gave up installing a new instance of Friendica, we were using existing one, which is available on:https://friendica.hackerspace.pl;
• we've focused on existing connectors to closed (but popular) media services: Twitter and Facebook;

• installing Facebook connector is straigh-forward, we did everything according to README, which was present in facebook addon directory in Friendica code tree;

• NULL

We were not able to use the connector at all;

• Enabling connector (as Administrator):
  • Settings → Admin → Plugins → Enabling Twitter (OK)
  • confirmed also via “select * from addon”, twitter enabled

• Trying to visit settings page for this plugin: twitter results in following error:

2013/01/26 19:27:33 [error] 19804#0: *14436 FastCGI sent in stderr: "PHP message: PHP Warning:  file_get_contents(view/admin.tpl): failed to open stream: No such file or directory in /var/www/friendica/include/text.php on line 438

• As a result, it was not possible of course to enable / configure connector per user.
