Hi there,

First, try re-generating project configuration settings from scratch:

  1. Close the IDE and delete the .idea folder and any .iml files from the project root folder
  2. Launch the IDE
  3. Go to File | New | Project from existing sources and choose the project directory as your source
  4. Wait for indexing to finish

If it doesn't help, reset IDE settings to defaults (a backup copy will be created in the process): File | Manage IDE Settings | Restore Default Settings
