Im a litle chicken to do that man I am running 1.39h and I have never upgraded for I did not create custom pages in the beginning and I put a lot of work and effort into this considering a while ago I did not know squat bout any of this. I red the read me file in the plug in and this sounds a little rough for me.
We run this on a few sites in 1.3.9h
What frightens you? As with any plugin, you do a full backup first.
In this case, there are NO over-ride files, so you just port the INCLUDES folder to your server's INCLUDES folder... Then run the install.sql .
You do not need to run install_UPGRADE.sql
I see Melanie Prough has upgraded the mod for ZC 1.5 - but as you are running 1.3 then you can ignore all references to 1.5
It's really simple to add... Takes less than 30 seconds to install this plugin...
Just FTP the FILES to your server
Then, in your zencart ADMIN, go to TOOLS >>> INSTALL SQL PATCHES and then copy and paste the "install.sql" text into that window and send it off.
As I say, you should backup your dbase first.
