Hello
I installed Q&A plugin, which is a plugin where people can ask quesitons and users can give answers.
It's located in a sub directory. All the other pages are fine, but for some reason I'm getting an additional left sidebar underneath the content in the center column. I have no idea why, or what ot look for to change it. If I switch back to default theme, it is not there.
Any ideas?

Not enough info to troubleshoot.
Atahualpa version?
WordPress version?
URL to site?
URL to plugin?

Hello
Newest versions of wp and atahualpa
plugin:
http://wordpress.org/extend/plugins/qa/

Posted a review but held by moderation?

Taking a quick look at the plugin, because of the way it is coded, it will not be compatiable with Atahualpa.

You may want to bring this up with the plugin developer.
