As webserver I'm using nginx. I can cause the site to crash very easily by clicking around on some links. I am using an up-to-date version of Debian Wheezy. All packages are installed from the standard repository. I have attached a backtrace, which is the same with each crash. It seems as if the error is linked with the facebook connector from friendica, as it crashes when I try to load the connector settings, or if I go to the network page, which contains statuses from all connected sites including facebook. https://github.com/friendica/friendica-addons/tree/master/facebook Thanks in advance for helping find a solution!
