Unless you used FileZilla to perform the upload of the plugin files which can cause this sort of thing then normally it would come down to some badly conflicting javascript.

Do you know how to use Firebug and the script console to check for errors because that would be the best tool. If not open the Firefox error console – clear it out – Open the forum admin FROM THE WP MENU and then click on SP accordion menu.

Does anything shw up in the error console? JUST the Errors tab only please

Error: $ is not a function
Source File: http://tedx.osu.edu/wp-content/themes/NomNom/includes/js/color_options.js?ver=3.3.1
Line: 3

and 

Error: Image corrupt or truncated: <unknown>
Source File: <unknown>
Line: 0

I’m assuming this means NomNom has to go? I’m not even sure what that is. The site was just handed over to me from a school organization. 

EDIT: NomNom is the theme. 

Well without being able to look at the source code being generated I can only take a guess and that would be that the theme is not only loading scripts without using the proper WordPress API but as seen from that error is using the ‘$’ shortname to call jQuery which is not the correct way to use it in WordPress.

So it would work until something comes along that uses the WP API properly and uses jQuery properly. And than bam!

You could probably prove this by switching briefly to the default Wp theme and seeing if it works OK with that

That was it. Thank you!

np. glad we could help.
