After wordpress upgrade a plugin is disabling stuff on my homepage.

Hello,

I upgraded the other day to the latest wordpress version, sorry I can’t remember which one I upgraded from, it would have been one or possibly two versions back.

I don’t have much knowledge of how things work so perhaps this is just totally a problem with the plugin and nothing anyone can help me with on here. After the upgrade I can not use the Digg Digg plugin, it stops the larger gallery header image I have on my homepage from working and it also stops all my drop down categories, EX. Asia, Europe, etc.) from working as well.

I have asked the same question on the Digg Digg plugin support, but I see they don’t respond a lot and have yet to get back to me.

If anyone can suggest how I can fix that, thank you in advance:) If this needs to be the strictly the plugin author I need to ask or my theme author please let me know that as well.
