There have been reports of some issues with the new guardian log reading infrastructure. I have a suspicion that some of the problems might have been associated with the <a href="https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=26963">h1fs0 crash</a> this morning. In any event, I'm looking into the issue, and will report what I find.
And to be sure, please make sure you're using the latest version of the client, which is r1541. This new version was installed on Friday to fix a couple of issues. You may need to log out/in to refresh.
