[WP-United] I think WP united may be disabling excerpt and images adjustment

I’m working in wordpress theming and have a site set up that will detect an image from the database and then set that image to be the background of a div using simple javascript.

I have this set up on my test site: https://www.heroicdreams.com/elder-geek/2009/09/02/interview-aaron-schurman-ceo-of-phantom-efx/ , and it works perfectly on all browsers.

But now I have implemented the theme on the client site which has WP running WP-united, the background image only works in IE and no other browser. https://elder-geek.com/2009/09/interview-aaron-schurman-ceo-of-phantom-efx-2/

Does anyone have any idea what could be the cause of this issue?

Also, I’ve made the change to the formatting.php file to make the excerpt only 23 words and end in … but it’s not changing the excerpts on the site. Is wp-united the cause of this?
