Joomla htaccess issue

I used the recommended htaccess from the Joomla directory to improve security on a friends site (I did created as a favor). However, since this change my chrono captcha does not appear. I have nailed it down to the htaccess and needing http://www.kickapoowild.com/components/com_chronoforms/chrono_verification.php?imtype=0 to have access to. However, my htaccess skills are not the greatest. Can anyone tell me what I need to add/take away to allow access to this url for captcha?

Hi a76erfan,

Please try commenting out this line:

# RewriteCond %{REQUEST_FILENAME} \.php$

Bob, I will try tomorrow night when I am on my computer again. Thank you for the quick reply.

Bob, still getting this error on that link reference

I ended up using the recaptcha option through various instructions on the site. I also switched to gmail as my smpt server as the joomla phpmail is less than stellar. Thanks for the support and the great form builder. Still the best there is.
