Blank Page After Login

My piwik installation was working fine up until a few days ago.

Now after I login, piwik shows me a blank page. No html source, no logout button, nothing.

I did not perform any updates to piwik or change it in any way.

Can someone help me fix this?

I HATE it when I figure it out right after posting a question.:X

It looks like something is up with the ‘all websites dashboard’ view. I changed it to view one website and the system loads up ok.
