blank main_page=checkout_process

Yes both are v1.3.9b They were downloaded less then a week apart. My concern is if there was any client specific data dropped into the code by the Zen functions or by the activation of the LinkPoint module. If not then do you think it should be tried?

Were you able to cypher any solutions from the cache data I supplied?

Always grateful for your help.

My concern is if there was any client specific data dropped into the code by the Zen functions or by the activation of the LinkPoint module.

Out-of-the-box, Zen Cart doesn't store any client-specific data in any ".php" files, other than the "configure.php" files which tell the software how to connect to the database where all the shop's sensitive data is stored.
I can't speak to whether any addons you might install might do differently though.

This is a heart breaker. I swapped class.linkpoint_api.php files between the working site and the problem site. Tested. Still came up with a blank page.

Checked cache again: [02-Jul-2010 10:00:02] PHP Fatal error: Cannot redeclare class lphp in /home/naturals/public_html/store/includes/modules/payment/linkpoint_api/class.linkpoint_api.php on line 49

See previous post for copy of line 49.

Does this mean the trouble is not with that specific file? I'm stumped and looking for direction.

Correct.

Fastest way to identify what's wrong is to compare all the files on that site against either the files from the working site or from the original Zen Cart zip.
Ref: http://www.zen-cart.com/wiki/index.p...Obscure_Issues
Identify all "extra" and "missing" files first, dealing with whatever anomalies you find.
(It's not uncommon for people to rename "abc.php" to "abc.old.php" and end up with similar serious problems because Zen Cart often loads all files ending in ".php". In such cases renaming the file to "abc.old" would have been a smarter choice.)
If the missing/extra check doesn't reveal the problem, then look at "changed" files to see what content differences are causing it.

Ajeh, I'm stumped. I dread downloading and starting again. Too much work. Is there anyone that can puzzle this through. I'll gladly compensate. My client is losing patience. Is there an additional resource I can tap? Or have you any direction for me to try?

Always thankful for help.

Thanks Sensei. I'll follow your directions. I'm on a Mac and just downloaded a similar comparison program, Differencia, now trying to learn how to use it.

Is it possible to know which files might directly impact class.linkpoint_api.php (the file named in the cache) or the actual blank file main_page=checkout_process ? Then just compare those few?

In what folder would I find main_page=checkout_process ?

[DrByte]

If it were that easy I would have suggested that sooner

Differencia does not work with php files so now I'm on to a new software called FileMerge which comes with Apple's Developer Tools, Changes App. It's supposed to detect even one space difference. We'll see.
