A functionality to preview of CMS doesn't work

[magentomeister]

Hello, 

I have upgraded Magento Enterprise Edition from 1.11 to 1.14.1. After that, cannot use preview of CMS correctly.

It will be redirected to the main dashboard soon, or it will just dispaly dashboard into 'preview mode window' after clicked button of preview.

Unfortunately there's no error message in a file 'var/log/exception.log'.

Also web browser cannot detect any errors. Does anyone know the reason why it occurs?

Have you opened a ticket with Magento support?

Hi, Brent, thanks, I should close this ticket because I've already solved by myself. Closing.
