Problem with below_body style/class applying themselves to body_wrapper div/class

[JohnD5000]

After uploading a new style from an xml file, the style works fine on the main page, forum.php, however on forumdisplay.php the main body elements are formatted according to the below_body class which i do not want. On the main page the appropriate styles are applied (body_wrapper) to the appropriate elements, but on forumdisplay.php and member.php, below_body style is being applied to most of the div that should have the body_wrapper style applied.

Any ideas?

See forumdisplay vs. forum.php below.

Thanks in advance for your help,
