Blank page when proceeding to checkout payment

Hello,

I noticed my website was showing up with a blank page when proceeding from the checkout shipping to the checkout payments page. So I researched through various forums and found out that blank pages are mainly caused by syntax errors. I'm fairly new to coding, so I thought I'd reach out to see if any of you would know how to resolve this issue.

On Safari the page is blank and on Chrome the page reads:

The website encountered an error while retrieving https://gonebeachin.com/index.php?main_page=checkout_payment&zenid=700c828b1bff2b903b4d11260e5691bf. It may be down for maintenance or configured incorrectly.
Error code: 500

I checked my error logs and read this:

[15-Sep-2013 14:53:18 America/Phoenix] PHP Fatal error: 1064:You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '( DROP UNIQUE KEY type_code (payment_type_code), ADD UNIQUE KEY type_code (payme' at line 1 :: ALTER TABLE zen_so_payment_types ( DROP UNIQUE KEY type_code (payment_type_code), ADD UNIQUE KEY type_code (payment_type_code, language_id); in /home/content/27/11720727/html/includes/classes/db/mysql/query_factory.php on line 120

Also I noticed when I save pages in my admin that when I save my pages I receive a blank page as well.

I believe this syntax error below applies to the admin:

[15-Sep-2013 08:41:44 America/Phoenix] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/content/27/11720727/html/adminurrhtcqq/define_pages_editor.php:121) in /home/content/27/11720727/html/adminurrhtcqq/includes/functions/general.php on line 22

Do I remove spaces in general.php?

Everything I do seems to lead to the same result of a blank page. Any help would be much appreciated. Thanks.

Define pages editor issue solved. The only issue I still need help with is the checkout payment portion of this post.

I have the same problem with blank page on continue checkout. How did you resolve it?

There is no "so_payment_types" table in Zen Cart.
Sounds like something from a Super Orders addon, which you may not have installed properly?

As with ALL blank-pages scenarios: http://www.zen-cart.com/content.php?124-blank-page

This happened to me not long ago. I saw that files were all of the sudden showing up, so I went to my backup folders and compared and deleted the files that showed up and have not had a problem since.
