Acrobat Security Error, could not open pdf file
Hi guys,
While at work repairing some gadgets, I had a hard time remembering some steps, so I decided to take a look on a manual in a PDF file, when I was about to open the file from our server, an error message appeared, sounds to technical to me that I can not understand, I pasted below the screen shot of the error message.
Acrobat Security
The document cannot be opened because it is protected by a security policy
from a server that is on your list of blocked web sites.
(Manage site access with the Trust Manager Preferences panel)
This is the first time that I encountered such error, and the error is also very technical that I don't have any idea, I browse the internet for same error message, but none was posted, that is why I posted this error to this site, in hope to get some solution to my problem.
Thank you so much.
