I am the webmaster for http://www.savannahtearoom.com. Like many, when I updated to the new version of MarketPress, I lost the store functionality. Following the advice of "Jude" in the support forums, I attempted to reinstall the previous version. Not only did this not solve the problem -- it is worse. MarketPress is no longer a "plugin" on my sidebar or anywhere.
I am now afraid ALL of our products, prices, store receipts, etc. are lost!
I am not a tech genius but I am fairly proficient.
This needs to get fixed ASAP!
