At the moment, I am able to see your entries without any problems, and there have been no other reports that I am aware of with that issue. If it's still occuring, try clearing your cache etc, maybe test in another browser... and if it remains an issue, or comes back, open a Support Request on it.
Hey ! Thanks for taking the time to reply to that. The problem got sorted out after a couple of hours, so I closed the support request. I dont think it has recurred since. Thanks although :)
That said, all of your entries are visible in the HTML source, so it looks like you messed something up while playing around with overrides. Remove those first, before opening a request.
