Edit order (orders.php) is blank after upgrade from 1.3.9h to 1.5.4

Hi Guys,

I have spent quite a bit of time trying to solve this one, tried looking for logs, winmerge to compare files (didn't go that well; a lot of differences so that route didn't show me a solution), here is what I got, if you have any ideas please share.

Zen Cart 1.5.4
Database Patch Level: 1.5.4
v1.5.4 [2015-02-01 06:26:59] (Version Update 1.5.3->1.5.4)
v1.5.3 [2015-02-01 06:26:45] (Version Update 1.5.2->1.5.3)
v1.5.2 [2015-02-01 06:26:27] (Version Update 1.5.1->1.5.2)
v1.5.1 [2015-02-01 06:25:43] (Version Update 1.5.0->1.5.1)
v1.5.0 [2015-02-01 06:23:03] (Version Update 1.3.9->1.5.0)
v1.3.9h [2011-03-14 20:23:14] (Fresh Installation) (Simple Scripts)
Done following the upgrade procedure in this Forum using the upgrade tool.

Server OS: Linux 3.12.32.1415814620
Database: MySQL
HTTP Server: Apache
PHP Version: 5.2.17 (Zend: 2.2.0)

No plugins/addons installed

Don't have logs other than the upgrade procedure where all reads "OK" after each line.

Basically what happens is when I am in the admin area in the customer's orders page and click edit it opens the page brings the header and drop down menus but the rest is blank. All works in the store and admin as far as I have seen, even the packing list and Invoice options work, only the edit page does not.

Thanks in advance.

1. The BEST fix is to upgrade your PHP to a modern version. Yours was retired many years ago. PHP 5.4 is the minimum you should be using "today".

2. In the meantime, you can try these 2 small changes:

   But you REALLY should get your host to upgrade your PHP, or have them tell you how you can do it for yourself.

DrByte,

Thanks! opening you forum and finding a good answer is priceless!!

I do use BlueHost so I can do just that, but please help me select from the additional extensions options what should I select, here is the list they show when I want to select the latest 5.4 version:

PHP 5.4 (FastCGI)
All files with the extension .php will be handled by PHP 5.4 FastCGI processes.
FastCGI for PHP makes all your PHP applications run through mod_fastcgi instead of mod_suphp. This eliminates the overhead of loading the PHP interpreter on every hit. Since it is always in memory ready for the next hit, the responses will be generated faster.
Additional extensions available for Installation:
Http
Magick Wand
Mail Parse
OAuth
OCI8
Upload Progress
IonCube
SourceGuardian

Thanks in advance!!

Zen Cart doesn't need any of those extensions.

Super thanks!! trying it right now.

Hi there,

Just did the upgrade now it shows:

PHP Version: 5.4.34 (Zend: 2.4.0)

But still the problem is present. I need to clarify that my page is not blank after log in, all seems to work in my admin area, it is only when I click on edit to edit an order (orders.php)

Any ideas what to do next?

Make sure the correct path is configured for the log files and is writable by the webserver. Usually with a partially blank page (under PHP 5.3.7+) an error log will be generated.

May also be worth using a tool such as Beyond Compare or WinMerge to see if (and how) your store (especially the admin folder) differs from a "clean" download of Zen Cart.

orders page and click edit it opens the page brings the header and drop down menus but the rest is blank

1. Is it the COMPLETE set of menu options? Or is a particular option missing?

2. If you click View Page Source in your browser, what's the last 10 lines of HTML that it's sent to the browser?

3. A partially blank page usually means PHP stopped executing, typically because it encountered an error.
   As long as the /logs/ folder is writable, it will write the actual PHP error to a file in the /logs/ folder, so you can use that information for debugging. Explained: http://www.zen-cart.com/content.php?124-blank-page

4. As lhungil has pointed out, what are all the differences in the files in your (renamed) /admin/ folder vs the original Zen Cart distribution files in the /admin/ folder?

5. What plugins/addons/mods have you done to your site? Which of those is interfering?

I will be comparing and uploading to make sure all files are there complete.

Meanwhile, where is the path for the logs configured?

Thanks.

in your configure.php files there is a define for DIR_FS_LOGS
If the define is missing then the system automatically calculates it to be the /logs/ folder in the same place where your /cache/ folder (and all other main zen cart folders) are located.
But if you've defined it to something invalid, then fix it.

logs and cache folders with 666 permission and still no logs. configure.php files don't have the define for DIR_FS_LOGS

all files look the same.

5. What plugins/addons/mods have you done to your site? Which of those is interfering?

None, I only have a template no addons at all.

I believe your /admin/orders.php file is NOT the same as the original /admin/orders.php file that comes with Zen Cart.
