Cannot figure out WSOD

I have the most perplexing WP issue I've yet experienced. As near as I can tell it's a problem with the db and not the WP code.

Here is my setup:
- Just Host web hosting
- WP 2.9.1
- WP e-commerce plugin 3.7.5.3 (latest)

I have a working installation here:
http://thedolly-mamas.com/pip

But this installation is getting the WSOD on both the wp-admin and browsing the site:
http://thedolly-mamas.com/retail

I cannot for the life of me figure out what is going on. Here's what I've tried:

- removed the plugins in /retail, but WSOD persists
- checked the wp-config.php for leading and trailing spaces, but there are none
- created a fresh WP install without any plugins at:
http://thedolly-mamas.com/wptest
This works and I go through the new install setup.
- took a mysql backup from /pip (known working db) and imported to /wptest. This causes the WSOD too.
- to see if I could pin it on the web host, I set up a new WP install on my personal web space and imported the /pip mysql backup. Same WSOD.

I'm out of options at this point and very frustrated. Does anyone out there have any suggestions?

UPDATE:
@cagdas The values of both siteurl and home in wp_options are what they should be:
http://thedolly-mamas.com/retail

@scribu Thanks for the tip. Now I've got a bunch of errors to sort through. Any help on deciphering?

Now that I have somewhere to go now that I can see error messages, I am going to point the /retail installation back to the original retail db and start troubleshooting from there. Will appreciate more input.

    1. Login to phpMyAdmin control panel.
    2. Click the database name that you use.
    3. Browse the wp_options table.
    4. Edit "siteurl" and "home" row as you want.

    I hope it will help.

    Did you try adding this to wp-config.php?

    define('WP_DEBUG', true);

    • scribu says:

      You'll need to post the errors here, for any deciphering to occur. :)

    • Joe Golike says:

      Ok, to set a baseline, I created a fresh WP install (with empty mysql db) here. I'll give you the url in a sec.

      I turned on WP_DEBUG and I got an error-free default WP blog.

      Then I uploaded the latest version of wp-ecommerce to the plugins folder, and activated it through wp-admin.

      Now I am seeing a bunch of errors, and this is on a fresh install of WP and a fresh install of WP-ecommerce. It doesn't instill a lot of confidence in me for wp-ecommerce to be generating all these errors by itself. Should I be worried about all these error messages?

    • scribu says:

      Errors that begin with Notice: are harmless, most of the time, but they usually mean sloppy coding.

    • Joe Golike says:

      Yeah I've known from the moment I first dug into wp-ecommerce php that the code was ugly. I've restored /retail to the WSOD condition to compare to the errors that /wptest is giving:

      http://thedolly-mamas.com/wptest/

    • Joe Golike says:

      Oops, here's the two installs:
      1) http://thedolly-mamas.com/wptest/
      2) http://thedolly-mamas.com/retail/

      The only difference is #1 has blank WP and wp-ecommerce plugin. #2 is using the last known good mysql db before I started getting WSOD. #2 is currently WSOD, but #1 is not.

    • scribu says:

      Did you enable WP_DEBUG in #2 ?

    • Joe Golike says:

      Oh sorry I'm trying to keep these various installs and backups straight and it's making my head swim.

      WP_DEBUG is enabled now.

    • scribu says:

      This is the reason why it's failing:

      Fatal error: Cannot redeclare class usps in /home/thedoll1/public_html/retail/wp-content/plugins/wp-e-commerce/shipping/usps-new.php on line 2


      You should report this to the developers of the wp-e-commerce plugin.

    • Joe Golike says:

      I deleted usps-new.php as it was a file that I had modified for my client's shipping needs. I thought renaming it would render it useless, but apparently wp-ecommerce is autoloading all php files in that folder?

      I am still getting a WSOD when trying to login to WP:
      http://thedolly-mamas.com/retail/wp-admin/

      I don't see any fatal errors. Any ideas?

    • scribu says:

      It's trying to do a redirect, but it can't, because of the notices.

      Comment out the WP_DEBUG line.

    • Joe Golike says:

      Commented it out. Weird, now it's loading apparently fine.

    Try deactivating your custom theme in /pip then export the data. Then when you import the data to the new site, activate the custom theme.

    • Brandon Dove says:

      Have you tried deactivating WP-Ecommerce now that you're getting some output?

    • Joe Golike says:

      See my reply to Scribu above.
