This is a test post – I uploaded/changed/deleted the files around 3:45pm on 5/10/19.  As of about 4:30pm, none of my updates are showing yet, and my deleted file is still visible

GLC-website-caching-test1-20190510-344pm – this was originally a solid YELLOW PDF but I replaced it with a solid PINK PDF.  Right now as of 4:20pm on 5/10/19 I am still seeing the yellow PDF when I click that link. 

• I can see the actual PINK PDF if I append  ?#  to the link – for example: https://www.glc.org/wp-content/uploads/GLC-website-caching-test1-20190510-344pm.pdf?tryagain shows the correct pink page

Here is a green page I uploaded and then deleted from the media library.  As of right now, it is still accessible even though I deleted it completely from the media library!
