+Contacts app hangs
+------------------
+
+When your instance is hanging when you open the contacts app you might be affected by `Nextcloud issue #33048 <https://github.com/nextcloud/server/issues/33048>`_
+
+As a workaround you can remove or override ``ErrorDocument`` entries in the ``.htaccess`` file:
+
+.. code-block:: bash
+
+ ErrorDocument 403 "Forbidden"
+ ErrorDocument 404 "Not found"
+
+You need to reapply these changes after you installed Nextcloud updates or after you executed the ``maintenance:update:htaccess`` command.
