@mojolazarus it looks like the xml expected by that code is not well formed. I mean, it's almost sure that the problem is not in your b2evolution but in the external server that it is trying to connect with.
Is that block loading a third-party plugin ?
What video provider is it trying to connect with (youtube, vimeo, etc) ?
Maybe you should also investigate if your hosting provider performed an update in the server.
