Can't view Collections [while logged in to Listal]

I'm no longer able to view my collections in any category (Movies, DVDs, etc).

For instance, this page should show me all the DVDs I own: robelanator.listal.com/dvds/owned

In Firefox, this page is completely blank. In Chrome, I get a "Server error 500...The website encountered an error... It may be down for maintenance or configured incorrectly."

Weirdly, the page displays just fine in Internet Explorer 11.

UPDATE: Okay, I figured out why it was working in IE11 and not in Firefox or Chrome. It's because I was NOT logged in to Listal when viewing in IE11. Once I log out of Listal in Chrome I'm able to view the collections again.

So, to clarify, the problem is that I can't view collections while logged in with any browser.

Looks like this issue has been addressed. Thanks!
