This is the entire error from the console. The preview window opens and the entire view is black. Tried in different layouts, same issue. Even tried it on a layout with no events, same issue. I did recently clear all my firefox cookies. That seems to be what started this, but unsure what the issue or resolution is. Thanks for any help!
