Child Theme style.css stopped working

Hi there,

Just moved my site from dev domain to main domain. Since then some of the changes in my child theme style.css won’t take hold/show up on the site.

I’ve tested by making changes in the parent style.css file and the changes happen. Or, using Firebug they change but not when I put them in the child style.css file. Any ideas?

And it’s only for some items I am adding, not all.

I can post my style.css file below. The elements in bold are the ones that won’t show up:

/*
