Starting about 45 minutes ago the following has been happening as a pop-up in the LR part of my screen:

Object Invalid Value: Object at URL 'http://mudcat.org/thread.cfm?threadid=147103' of type 'article' is invalid because the given value '117759614949748' for property 'fb:admins' could not be parsed as type 'fbid'.

I have NO idea what it means.

I also get 'ads' like

"mudcat.org Traditional Music and Folklore Collection and Community
4 people like this.

That's new.
