Cross site request forger (XSRF) Attack Detected

I recently moved to a new office, I can send mail and save changes in leads at home but when I do it at my office, I get the Cross site request forger error. I followed the instructions, and added exceptions for saving changes etc… Works fine at the office. What I can’t do is send email or even access the setting to add my mail server. At home or on my mobile data, I can send emails and my mail server is showing. You guessed it, it doesn’t show up or work at the office.

I’ve tried to add an exception using the IP address from my office using:


but it doesn’t work.

What I believe: The network at the office has a server running which would trigger the Cross site request forger, adding an exception for the IP address doesn’t work though.

Does anyone have any similar experiences and resolutions?
