Can't configure conference rooms in 2.5.7

Hi, using spark 2.5.7, after creating a conference room the server keeps the room “locked from entry until configuration is confirmed”. However, when I go to Configure Room, no matter when I enter there, clicking update does nothing.

The debug console reveals that no messages are sent from Spark at all when I try to update the room configuration. Hence, the room is never unlocked. Is there something in my server’s room configuration form that’s preventing Spark from sending a completed configuration? I don’t run the server, so I don’t have a lot of details on its setup. Here is the XML of the room configuration form sent to me by the server:

  • No logging

  • No moderation

  • Up to 30 participants

  • No password required

  • No invitation required

  • Only admins may change the subject

To accept the default configuration, click OK.
