Login page blank and Error on page

Hello everyone,

When I try to create a dummy login account in my new zen cart installation, all I get after clicked the "Create an account" link is a blank background and an error message in the Windows status bar saying that there was an erro on the page.

It looks to me like this might be a JavaScript error, but I'm not at all sure.

Any ideas what might cause this?

I just opened up the page in Firefox and discovered that the error is getting in the way of comment tags, and so I was able to see a bunch of script displayed on the page. Along with that stuff, I could see that actual error:

Fatal error: Call to undefined function: zen_js_zone_list() in /home/windncom/public_html/shop/includes/modules/pages/login/jscript_addr_pulldowns.php on line 32

It looks like I'm missing a script file...

What do you guys think?

After using the Developers tools and serching for zen_js_zone_list, I found it in...

/public_html/shop/admin/includes/functions/html_output.php

but I'm not sure what to do next. :(

No thoughts on how I might get around this?

Just in case this or a similar issue is experienced by someone else, and in case this will help, I managed to trace the problem described above to an issue with an automatic install feature that my web host used to auto-install and configure zen cart for me.

To fix the problem, I just deleted the faulty installation and re-installed everything manually.
