checkout_confirmation crashes!

When I reach step 3, checkout confirmation, the page loads up with an unfilled template as shown below:

I can edit the actual page tpl_checkout_confirmation_default.php, and those changes do show up, but I want to know why this page is not displaying properly?
My checkout process does work both in test mode and production. Payments are sent and processed by my merchant account and everything from emails to invoices being recorded occurs successfully. The only issue is how this checkout confirmation page doesn't load correctly. I've even re-uploaded the page from the installation and it's still broken. Please help!

I'm using
Zen Cart 1.3.8a
Linux 2.4.32-grsec+f6b+gr217+nfs+a32+fuse23+tg+++opt+c8+gr2b-v6.194 Database: MySQL 5.0.45-log

PHP Memory Limit: 90M

How can I fix this problem? Any suggestions?

Bugs are issues that occur with every Zen Cart site. This problem is specific to you.

Anyway, it looks like some of your language files are messed up, or possibly not even there!

Check includes/languages/english/checkout_confirmation.php to see if it exists. If it does, compare it with that of an original for differences.

Or it might be
includes/languages/english/your_template/checkout_confirmation.php

Steven,

Thanks for your suggestion! I discovered that I was missing [ includes/languages/english/checkout_confirmation.php ] after all.

Now that I test it out I'm getting a new error that I never had before in test mode :
MODULE_PAYMENT_AUTHORIZENET_AIM_TEXT_AUTHENTICITY_WARNING

Also the combined shopping cart used to display text now it just warns:
WARNING_SHOPPING_CART_COMBINED

It looks like more english language files are missing where they weren't before.

I'll keep digging around but if anyone has any answers please help. Thanks!

Whenever you see some text like that which is in capitals, it almost always means there's a missing or damaged language file somewhere. What you need to do is download a fresh version of Zen Cart and compare all its language files with those of your own. To make this easier, there are tools available which can be used to compare files and folders to check for any differences. Many people here use WinMerge, which is free.

Seems like my english.php file in the english folder was missing this declaration:

define('WARNING_SHOPPING_CART_COMBINED', 'NOTICE: For your convenience, your current shopping cart has been combined with your shopping cart from your last visit. Please review your shopping cart before checking out.');

Very odd. The warning WAS popping up before I corrected the step 3 bug, then it went missing. Strange.

In fact, it would be prudent to check all your files, just in case anything else is missing.
