I tried to add sueden.social/#0 /var/www/freunde/src/Model/Contact.php(3304): Friendica\Model\Circle::addMember()
#1 /var/www/freunde/src/Module/Contact/Follow.php(192): Friendica\Model\Contact::createFromProbeForUser()
#2 /var/www/freunde/src/Module/Contact/Follow.php(69): Friendica\Module\Contact\Follow->process()
#3 /var/www/freunde/src/BaseModule.php(231): Friendica\Module\Contact\Follow->post()
#4 /var/www/freunde/src/App.php(595): Friendica\BaseModule->run()
#5 /var/www/freunde/src/App.php(190): Friendica\App->runFrontend()
#6 /var/www/freunde/index.php(22): Friendica\App->processRequest()
#7 {main}

Is this problem already fixed in the develop version or is it a problem with my server?
