I have this installed on my site, but when I turn on the sidebox, I get the following error on my site:

1054 Unknown column 'p.products_date_added' in 'where clause'

I posted this in the old forum and someone said that it was not compatible with my version of zencart, however, I just installed it on another zencart store, same version as mine, and it works beautifully with no modifications. I am using 1.2.6. Can anyone think of any other reason why I'd be getting this error? Could it be somehow related to one of the other mods I have installed?

Thanks!
