Customize F5 APM Logout/Error Page Text

Hi all

 

We are using F5 BIG-IP 12.1.2 (Build 1.0.271) and busy deploying the Exchange 2016 iApp with APM. For security reasons I am trying to make it difficult for end users to see that we are using F5 APM i.e. customize the APM login/logout/error webpages and take all the F5 text, headers, footers, and logos out.

 

I have managed to do this for almost every webpage (basic, general, and advanced customization with templates), except for logout/error pages. I can not find out how to remove the text "Thank you for using BIG-IP." (see screenshot below). Unfortunately this is a dead giveaway ;)

 

Can someone point me in the right direction? Where can I change/remove this text?

 

Thanks in advance :)
