thanks... but I reloaded everything and still cannot figure it out.

[DrByte]

So, what's in the logs? (see the link I gave you earlier)

It may be necessary to get support for your custom checkout addon from the author, since that's not part of core Zen Cart code.

[gibow]

sorry... I guess I need to know where to look at the "logs" ? I got the template from the free software downloads section the zencart website:

http://www.zen-cart.com/index.php?ma...oducts_id=1740

thanks for any help.

It's in your cart's root directory, at the same level as the admin and includes folders, scroll down past all of the folders to the individual files. It's called error_log. That will tell you what's broken.

Here are the error logs... so how to I determine what is wrong, and go about fixing it?

Judging by the dates on those error messages you're looking in the wrong place.

Go back up to the link I posted for you earlier. It gives you specific instructions on where to find the myDebug-xxxxxxx.log files which Zen Cart records when PHP errors are encountered, which typically triggers a blank screen.

Does this look right?

Well, those are errors reported by Apache, not by PHP.
And, yes, you should fix those.
They're telling you that there are problems with the stuff you've added to your .htaccess file.

Zen Cart has some .htaccess files located in the various subfolders of the site, but not in the top folder. If you have a .htaccess file in the top of your site, then you've added that yourself somehow. And, if that file is causing errors it might be best to rename the file until you can come up with working content instead.
The most common reason why people add .htaccess files is to add URL rewrites to their site because they think search engines need it, when in fact they don't.

But that's somewhat unlikely to be causing your checkout page to be blank. The blank page you mention is caused by something wrong on your "fast and easy checkout" addon that you've added to your site. Either figure out the PHP errors it's causing, or disable/delete it from your site until you can set it up to work properly in a test-copy of your site that doesn't affect your live store.
