This is pretty weird. I have a few dozens WP sites I manage via InfiniteWP and many use WooSidebars. I love it. I recently did a blanket update to 1.3.1. Today a client contacted me that her pages had lost their formatting (theme is Headway 3.x) I had recently added W3TC and so went into plugins to disable it to see if that was causing the issue. I noticed WooSidebars was disabled. I re-enabled it and voila, the formatting issue was fixed! YAY! So no problem I need help with. I just wanted to ask why updating left the plugin deactivated? That seems like a bad idea. I need to go check all my other sites to be sure it's activated. Is this a new "feature" or a bug?
I thought mentioning it here might help others too.
