i build a shop with e-commerce. (http://www.u-tees.me).
woocommerce and artificer by woothemes.
when i activate almost any plugin, the left sidebar disappears from "shop" page, which is also my homepage., or shows only 2 of the 4 widgets i have there.
i can't activate plugins like jetpack, contactform 7, sharethis, google analytics, seo, cache etc.
i started a new installation, DEactivated EVERY PLUGIN (including akismet and hello dolly).
The moment i add valuable plugins like those above, the sidebar disappears. i have a couple of meaningless plugins i managed to install without having the sidebar disapper (they are from the level of hello dolly).
i have a feeling it started when i upgraded to wp 3.5, but i'm really not sure.
How do I fix it?
