Thanks DNNMonster, tried to use the Content Injection Module as it sounds very promising. Downloaded but when I try to add it says not compatible with host application. According to this https://wnsinj.codeplex.com/ the requirements are:

DotNetNuke version: 06.00.00 and up
SQL Server version: 2005 and up
.Net Framework version: 3.5 SP1

I meet the requirement so it should work.

Just checked the manifest WillStrohl.Injection.dnn in the DNN package

It says requirement is

07.02.00


I am running 6.2.9 so that's probably why it doesn't work. The mismatch on requirements doesn't create much confidence in this module. Any suggestions?

Ok, I understand. If it supported the version it said it would support I would certainly give it a try.

That's a fair question :-) I did try to use a higher version but it failed as the host was unable to support the requirements of version 7. I am simply waiting until they can support it and there is enough need to upgrade without adding more issues.

In any case, at this point I would not be upgrading and would simply want to find a simple solution to the HTML header problem which to be honest should not be that complex.
