Hi,
Flashlight is compatible with WooCommerce with the stable version. What that means is, when you see in WordPress a notification that a new version of any plugin (or the Wordpress framework itself) has just been released, it is never a good idea to click the update button on a live site. If you do, you are gambling that whatever updates have been made are 100% compatible with the theme. Please give us time in order to test and verify if that's a fact while minimizing your risk.
Please setup a development website ( most have it at a location like dev.your-domain.com ) - which is a mirror or your live site with its own copy of the database ) and this is where everything is tested first before the live site. WooCommerce just had a major upgrade to v2.0 and in the past 2 weeks had 5 version updates fixing the various problems and stabilizing. Kriesi has been doing a commendable job keeping the themes compatible with their latest releases.
My rule of thumb with any theme, plugin, or Wordpress framework update, is to wait around 2 weeks to a month before upgrading to ensure that the compatibility issues have been ironed out first ( by comparison, your host may wait as long as 12-15 months before upgrading their versions of mySQL database, PHP, or Linux to ensure everything has stabilized. )
I have notified the support team about your request for paid support. If you need something urgently I would recommend freelancer.com , peopleperhour.com or any of the other sites that allow high caliber developers to bid on short term dev work, as today there is a good number of developers very familiar with Kriesi's Avia Framework as well as WooCommerce.
Thanks,
Nick
