This was caused by a bug. There has been quite a few bugs for the web profiler caused by its dependencies being updated.
In my silex application I have monolog, and profiler working together and am using https://github.com/silexphp/Silex-WebProfiler for the web profiler provider.
I can access the data by going to the routes it mounts but I would like to add the toolbar it makes too my other pages. Any idea on how I can do this?
