Thanks for your post mc12345678.
This is site #2 that I am working on upgrading. It has taken a couple of weeks just to figure out how to grab a full db backup. (something the host CS won't tell you how to do). It has been years since I have gotten fully involved 'coding' the website. It's one of those things where you set it and forget it, like reading the book to setup a new printer or network. If I got new ones tomorrow, it would be a new learning curve just to find the IP#s .... at least I know where to look. Zen is not that much different.
Site #1 had room for more than one database, and I needed an upgrade with a template that is mobile friendly. It is now up and running, but starting from scratch, I only have 100 of the 800 items loading in the cart.
Site #2 is a host bare minimum site, and only has room for 1 SQL database. You were talking about addons that touch the database. One is GoogleFroogle, and cowoa. From what I have read, the upgrade instructions are clear about removing add-ons before upgrading. Getting 1.3.8 to run on localhost is challenge enough. I must have re-loaded the install a dozen time, and now the admin works, but the webpage is still blank. I really want to get this right before moving on to the upgrade to my host. I don't want to start this one from scratch either as it has over 500 digital downloads, and setting up attributes for file downloads is an added pita.
So that's the thing. Neither of those two plugins as far as I've seen would prevent setting up a bare ZC 1.x.x site, dropping the tables for that store, loading the tables for the old store, continuing the upgrade process using zc_install.
As for the single database to perform an upgrade on, not exactly easy, but it is possible with proper "change" management... Heck, hadn't really thought of this side of things and not sure if it would work without first doing the upgrade, but the zc_install process does allow for database table prefix changes... If it could work, I would backup the current database, use that process to rename the current database, then reupload the copy of the current database, then do an upgrade on the new copy...
Alternatively, backup the database, if it has no prefix, then unfortunately go through the 100ish tables using a search and replace of 'create table ' for 'create table zen_' where the single quotes wouldn't be used, but are there to show the space following the word table as part of the search and replace...
As for your local environment. Well, you need pretty much all "old" software for it all to work as necessary.
The white screen with no logs, you need to enable a little more information to be displayed because it would seem that a problem is occurring before the ZC error logging has picked up. See:http://www.zen-cart.com/content.php?124-blank-page
