Error "Failed to initialize the editor as the document is not in standards mode

[Terry31459325f5az]

ColdFusion pre-compiles all code when cache is turned on. It also places a comment (<!--- servername/index.cfm---> ) on the first line of the page when cache is on. !DOCTYPE...> no longer works since it is now on the second line. This causes the !DOCTYPE to NOT be in Standard mode.

How can I remove the comment line so the !DOCTYPE is the first line?
