Just had a painful weekend trying to get the Trust Logo to work and the solution is so easy I thought I’d post the solution so others can avoid my suffering.
Don’t use Chrome to generate your scripts! Use IE.
During the copy/paste process, Chrome was replacing several characters with the hex character A0 for reasons unknown and although the code and test files looked identical in both VS2010 and Notepad, these rogue characters were breaking the javascript and stopping the trust logo from displaying.
After I got it all going, I went back and tested using a hex editor and worked out what the issue was.
Comodo support were awesome and solved my problem quickly. Thanks guys.
