I installed 11.1.1 on Mac OSX and set up a new project which contains a mix of PHP, Python, JS, YML, etc. files. All file types load and edit fine, have correct syntax coloring, and the margin on the right indicates TODO items and Git changes. It never shows results of inspections though for any file type even though there should be (a previous install of PhpStorm - now uninstalled - worked fine and showed them). The icon at the top of the margin shows an eye and the tooltip says "Performing code analysis: no errors or warnings found so far." In addition, in the Inspections tab of the Project Preferences dialog, it never shows the list of inspections to configure: it just shows the word "Loading" and a spinner - this goes on forever until I choose another tab or close the dialog. The CPU is not busy during that.
I'm new to IntelliJ so I'm looking for help diagnosing here before assuming it's a bug. Where should I begin to diagnose this?
