if i try to access the page that generates the captcha image directly:
wavt_captchasecurityimages.php
i get a 403 access forbidden error message.
this is probably a permissions issue. using File Zilla or another FTP Program to access the site files, you will need to change the permissions of the webassist/ directory and all files and folders under it to 755
The headers already sent error is caused by white space between php tags.
the error is reporting the problem around line 4 of the episode.php page:
output started at /home/hantsle/public_html/podcasts/episode.php:4
