I added a left sidebar to my Activity page. The sidebar contained the Upcoming Events widget from the just updated Events + plugin. When I went to view the page, from the View Page option on the edit form, my browser window went completely white. I tried going to my dashboard, but that page is a completely white browser window also. It seems that my site has completely been replaced by all white pages. Do you have any ideas of what I can do to restore things to normal?
