 * Hi,
 * I was validating my pages and on just one page came up with the following error–“
   Sorry! This document can not be checked.” due to the Error 406 Not Acceptable.
 * When I googled this most folks suggest that apache mod_security may be tripping
   up on a term in the URL and they suggest inserting the following into .htaccess:
 * SecFilterEngine Off
 * That doesn’t work on my shared server b/c apparently they don’t use mod_security.
 * Also, when I move the offending page into a lower directory instead of assigning
   it a parent, it doesn’t get an error 406. After playing around with the name 
   of the url, it seems that some combination of “classes/opt” is what triggers 
   the 406. (The original url is “classes/optimal-positive-birthing”. If I change
   the url to “classes/ptimal-positive-birthing” without the ‘o’ it doesn’t show
   up. It shows with “classes/opt” but not “classes/op” and “optimal-positive-birthing”
   without classes is also fine.)
 * I guess I can change the name, but the specific name is important to the client
   and I’d rather identify the problem.
 * Any suggestions would be great! Thanks in advance.
