Migrated to Coldfusion 10 - PQgrid stopped displaying data

We recently migrated to CF 10.  Using jquery 1.11 and PQgrid, I displayed a list of people.  It has stopped displaying the list of people.  On the CFC call I get the following error:
 ColdFusion was unable to add the text you specified to the output stream.  This is probably because you have already used a CFFLUSH tag in your template or buffered output is turned off.

If I take out my cfhtmlhead tag that puts the Javascript in the head, the grid doesn't show at all.

All of the pages on the site go through a default template that puts a dashboard at the top of the page.  Everything else is added using cfinclude.  That's why it's necessary to use cfhtmlhead.  There are other things I could do to get the javascript in the head, but I want to understand the problem.

I had the same error on another page and change the Maximum Buffer Size to 4096 to solve the problem.  Something has to be wrong when it takes 4mg to load a page.

I had to wrap my OnRequestEnd.cfm to check for .cfc so it won't add html after a function call.

There is a configuration setting that is necessary for the <cfflush> tag to work properly with the web server. On the Configuring web servers in Windows documentation page, under the Configure IIS for ColdFusion in Windows section, among other things it states:


To disable webserver buffer, change the is_buffer_enable to false in the cfroot\config\wsconfig\1\isapi_redirect.properties file. Disable webserver buffer if you want cfflush to work over an IIS connector. If your application does not use cfflush, set it to true for increase in the performance.
 
You will need to restart IIS for this change to take affect.

I'm not sure what the performance ramifications are of disabling this setting. You will need to do some load testing for your particular environment to see.

I'm not using cfflush.  I am using cfhtmlhead.
