Google Checkout logo not showing on Zen Cart checkout page?
March 23rd, 2011 currentlyOfflineThis is a funny one and might save you some time 
If you’re trying to install Google Checkout module to you ZenCart store and just can’t see checkout button, there is one thing you should check. It’s not your fault ( just a little bit ) I guess many of us are so used to smooth module installation on ZenCart, that we are just copying module files and the hoping that everything works. ZenCart fault - definitely not mine And there is another one: unlike most extensions this one has a folder /templates/YOUR_TEMPLATE/templates so just copying the files will create folder called YOUR_TEMPLATE and simply won’t work – module developers fault, not mine again
So try copying folder by folder next time and I’m pretty sure you’ll see a long awaited result.
