问题 I upgraded Magento 1.7 to 1.9 and after upgrade the add-to-cart doesn't work anymore. It is not connected to the form_key! Why i think it is a database issue: I used clean magento 1.9 with clean database and created one product, add-to-cart works fine. I connected this magento with the database i upgraded and add-to-cart didn't work. So clean Magento with "old" database doesn't work on add-to-cart. Has anyone an idea how to solve this? I don't really want to use a clean database and move data

问题 I have an Application written in GWT 1.4.6 Is it feasible to up grade it to GWT 2.0? Where can i found the older versions of GWT i.e. 1.5, 1.6. Do i need to up grade version by version or can i straight away up grade to 2.0?? 回答1: My suggestion is also to go straight to 2.0.

问题 I've been using Cassandra 2.1.7 and For some reason I upgraded to 3.0.12 and later realized that some dependent apps won't work with 3.0.12 and I downgraded and using C* 2.1.7 as I was using before.

Appreciate your help. 回答1: When you upgrade from 2.x to 3.x you have to run upgradesstables command in nodetool. I assume this is what you did. Now when you

问题 I'm building my first WiX installer after becoming sick of the sight of Wise For Windows Installer! I've built the installer and that works fine, but now I need to get it to perform an upgrade from the previous version of my app. While I can find plenty of post about setting up WiX do perform upgrades, I can't find anything telling me how to do it when you have a previous installer made using another tool. Do I do it the same way? Do I need to get upgrade codes, etc, from the old installer?
