bp-social child css not working after WP update

I just updated WP and bp-social themes and all the child css changes I made are no longer showing up on the site.

all I did was update. I have searched forums, but cannot seem to find the same problem, and help on where to start would be appreciated

I have deactivated and reactivate the child theme and checked the permissions on the css file.

thanks
