I am in the process of upgrading my site from zencart 1.5.3 to 1.5.5b.
I have a test location where I am doing the upgrade. I did a backup of the db of my live site, and restored that data to a new db, since I want to keep all my customers, products, orders, etc.
I started with a fresh version of the code for 1.5.5b, ran the upgrade scripts, and then installed the winchester responsive templates.
Now I'm adding in a few addons that I had in my old site.
Everything was going fine until I attempted to install the 2.1.5 version of Ultimate SEO Urls.
I think the problem is that I had an older version installed in my live website (I'm not sure exactly what version. It doesn't display the version number in the admin), and I didn't remove any database stuff from the upgraded version before attempting the installation.
What I did is, installed all the files as per the instructions (uploaded the new files, uploaded the .htaccess, logged into the admin, uploaded the install files, clicked on a link in the admin). It said that it upgraded successfully. (That was my first clue that I had messed up. I was trying to install, not upgrade, but I forgot that the db contained the old version of the module.)
I then accessed the upgraded site, and none of the urls were rewritten with the seo urls.
I looked at the ultimate seo configuration page in the admin, and I didn't see anything that needed to be changed there.
So I thought maybe I needed to go through the uninstall process, and then reinstall.
So I uploaded the uninstall files, and attempted to access the admin part of the site, and now I just get a blank page.
No errors logs are showing up. I even tried following a suggestion I saw in order to see any errors showing up in the browser. I added the file:
Code:
includes/local/configure.php
with the following contents:
Code:
<?php
define('STRICT_ERROR_REPORTING', true);
but I don't see any errors, just a blank admin page whenever I try to access any pages in the admin side.
I tried uploading the uninstall files, accessing the admin, uploading the install files, accessing the admin, but no changes. I still just see a blank page for any admin page, and no error logs.
But since I'm not successfully accessing the admin, presumably nothing is really happening there.
I have seen suggestions of removing all previous versions of database changes, but I don't know exactly what that entails.
It would be great if someone could tell me all possible database stuff that I should look for to remove, that might fix this problem.
I do have the db backup that I made of my original 1.5.3 site. But unfortunately, I didn't back up the db right before attempting to add this module 
I know, major handslap! I really should have done that.
But it would be so much easier if I could recover from this situation, rather than having to start from the 1.5.3 db backup.
Also, one other piece of information is that I did have some numinix modules installed, and I think that changed the way some of the admin modules worked. I'd be happy to remove that since I'm no longer using it.
Does anyone have any suggestions? I'm pretty handy with phpmyadmin. If someone could please tell me all the db stuff I should look for to delete, then I can go in and do that. Any other suggestions?
Thanks in advance for any help with this.
