Can't install profiler symfony flex
问题 I'm unable to use the symfony profiler after running composer req profiler I'm using symfony/skeleton in version 4.0 beta, but i remember having the same problem when i tested it a few months ago in 3.3. The toolbar isn't working, message here : An error occurred while loading the web debug toolbar. Open the web profiler. And when click on "open the web profiler", i have a 404 error. If someone resolved it, thank you for your help. If not, I'll report a bug while this is still in bêta. About
