title: ABCPDF6 issue: "HTML render is blank" but web page output is fine
body: <p>Like the title says, we are using ABCPdf6 to render PDFs from XSLT.  Everything was working fine, but now we are getting an error that states "HTML render is blank".  Using a browser (tested on IE/Firefox/Chrome) I am able to browse to the generated HTML (formatted XSL) and it displays perfectly fine in the browser.  ABCPDF6 is not able to convert the file.  I have tried giving control to the page that outputs the XSL, but I am still getting this error.</p>
  
  <p>Does anyone have experience with ABCPdf and have encountered this before?  The code was working fine before without a problem, and another page that uses the exact same generating code (even pointing to the <strong>same</strong> placeholder page that spits out the HTML!) is working fine.</p>
