Just a quick thing I found in the left sidebar. This is what I see upon visiting the site, or initially logging in. All is as it should be I believe.

If I select Tribe of Judah from the dropdown list and click 'enter site' I get this result. I'm not sure if the list disappearing is intentional or not.

However, if I select any other option from the list and hit the 'enter site' button/link, I get this message.

There are a couple things that could be going on there, first it could be a design thing where access is limited by security access, or it could be a result of there not being any content available (I'm leaning toward the latter). Whatever the case, it is throwing an error whether it should or not. I'm continuing on the assumption that an error is supposed to occur.
Now continuing on to the last screenshot, if I cause the error to happen and then proceed to select Tribe of Judah and click 'enter site', the error stays.

That is an easy fix as it appears that when the onclickevent (or whatever you chose to call it) is fired, the error message's visibility isn't getting set back to false.
tested on chrome and firefox.
