I’ve already seen this workaround but was quenched by the info about “/apps/dav/lib/Connector/Sabre/”. That I didn’t find in my ownCloud instance.
I did now implement the following change:
diff --git a/apps/dav/lib/Server.php b/apps/dav/lib/Server.php
$this->server->addPlugin(new CorsPlugin(\OC::$server->getUserSession()));
//$this->server->addPlugin(new CorsPlugin(\OC::$server->getUserSession()));
And now it works! ![]()
