“Visual” tab not working

Sometime within the last week, I can no longer click on the “Visual” tab while editing pages on my site. The tab is there but nothing happens when I click.
I tried several different browsers, several different themes, and disabling plugins but none of that worked. All of my themes and plugins are up to date.
