Title: Assets page "An unknown error occurred"
ThreadText: # Assets page "An unknown error occurred"
  
  (Asked by: username_0 on 2018-12-10)
  
  I'm suddenly unable to load my site's assets page. All of my asset sources are local, and loading the main assets page or any source folder or subfolder results in "An unknown error occurred." being displayed. No images are displayed. The assets section of the CP had previously been working fine.
  
  I can still see my assets when uploading an asset within an entry editing screen, though.
  
  The relevant log info (I hope) is below. Seems to be an issue with Imager, which I think was updated recently:

  As noted in the comments, sounds like you've got an error in your Imager config (prob an incorrect value set for the [`imgixEnablePurgeElementAction`](https://github.com/aelvan/Imager-Craft#imgixenablepurgeelementaction-bool) option or one of the lines close by).
