** Updated: This issue should be resolved with our August 2016 update. If you are still having issues, please read the suggestions below. When replacing a file, do not rename it with a different name. This can cause the system to keep on older file and not over write it.
There are a couple of ways you can troubleshoot this issue:
Wait 15 minutes for the varnish cache to clear and then click SHIFT + refresh in your browser. Or you can immediately click SHIFT+ Refresh in the pdf window and you will see the updated file.
Make sure you replaced the file by going into Site Content > Browse > Files. Click on the Edit link to the right of the file you want to replace. At the bottom of the window, there's an option to replace the file. Click the Browse button and find the replacement file (click Open to upload the file). Click Save when you upload the replacement file (with the same file name). Now open the file in the browser by clicking on the link. If you see the old file, hold down SHIFT + Refresh at the same time in the browser. You should now see the new file displayed in the browser.
Go to Admin Bar >Settings > Global Settings > Cache/Reindex and click Save.
You can delete the old file, and re-upload the replacement file, wait 15 minutes for varnish cache to clear and then click SHIFT + refresh in your browser (this may require a few refreshes).
- You can make your PDF a read only Word doc. When you go to Site Content > Browse > Files, you will notice there's a an edit button next to the file. Click on edit. At the bottom of the window, there's an option to replace the file. You can keep replacing it with updated read-only Word docs.
