Uncaught TypeError: Cannot redefine property: safeSessionStorage

[shaun_9858]

Hello everyone,

I hope someone can help me here. I have Adobe SDK PDF View embedded on my web application to view and mark up PDF files.
Everything was working fine until yesterday. Today, when anyone tries to open PDF files that are saved on the web server, they can't view the PDF file. The console log in the browser is showing the following error message. 
Uncaught TypeError: Cannot redefine property: safeSessionStorage
at Object.defineProperty (<anonymous>)

Please help. 

Thank you in advance.
