Admin blank page - CEON URL mapping

[saplanet]

I am experiencing admin black issues, when deleting a product.

Add-on:
CEON URL mapping
Template:
Westminster NEW

At first, I had problem with copying and editing product:
1. After copying, it returned with blank page, but product is copied after hitting ‘back’ button
2. After editing a product, and hit ‘update’, it returned to blank page

I managed to solve the problem, it’s a merge problem with these files:
/admin/includes/modules/copy_to_confirm.php
/admin/includes/modules/move_product_confirm.php
/admin/includes/modules/update_product.php

It appeared that CEON URL mapping code conflicts with the new 1.54 file.

The current problem:
1. Moving product and delete product, it returned with blank page.

Please help me look at the merged file of ‘move_product_confirm.php’:

3. I know delete_product_confirm file is not in the change log, but since the upgrade, the delete function also returns with blank page.

My current update_product.php looks like this:

Appreciate your help. Thanks!

I managed to find the problem, but I am not sure if I had solved the problem.

I reverted this file back to my original edited file: /admin/includes/functions/general.php

But there are still blank pages whenever I need to update changes on admin (including store setting, layout etc).

[mc12345678]

Technically this should be discussed in the thread for CEON URI mapping to receive the most visibility and possibility of resolution. Undoing the changes of ZC 1.5.4 is not a proper solution to support a plugin that is not yet uppdated to support ZC 1.5.4. Further because JSWeb has taken over the original product it may be necessary to reach out to them to obtain a proper resolution or to find out their plan for correcting the issue.

[saplanet]

Thank you for the direction, will find the support thread to post it there instead.

[saplanet]

Oh, but because generally, other admin pages are also going blank after hitting update/confirm, therefore, I wasn’t certain the source of problem.

Blank pages === myDEBUG log file generated

Look in your store's /logs folder for these files that will point you to the offending PHP module/line. If you post the contents of a myDEBUG-adm type file, be sure to xxx-out your admin folder's name first!

I’ve checked many times, there is no myDEBUG log file generated. The actions will still go through, but it just hit a blank page, and I have to go ‘back’ to return to admin; or to re-enter the address bar, and it will return to main admin, instead of where it came from earlier.

Saw the other posts, same situation, that there are several reporting blank admin pages (although the thread is completely chaotic with no facts, reproducible actions provided, etc...), and it may have been worthwhile to indicate that attempting to merge CEON URI Mapping into a version not yet supported by the module could lead one to identifying that their issue is with the same software, it further seems that those reporting a blank admin are not having it blank in the same scenario(s) as you've identified.

FYI, the forum thread for CEON URI Mapping is: http://www.zen-cart.com/showthread.p...I-Mapping-v4-x

but be forewarned that responses may repeat what I've said above.

As for the lack of error logs, verify that your logs directory is properly identified in your admin/includes/configure.php file... An example path is provided just above the define for it, be sure that it matches/relates to a true physical directory... (Could also temporarily place a problematic file in your admin/includes/functions/extra_functions file and see if an error log is generated..)

One last thing, be sure that in your "checking" for the error log(s) that you are looking in the logs folder (I can't see the previous post regarding where to look because I'm in edit mode) previous versions of ZC (1.5.0 and below) used the cache directory.

[saplanet]

Thank you very much for the link to the support thread.

You are right, my silly. I had someone done the previous upgrade, and I didn’t realise that the debug files are now in /logs, it was in /cache, so there are tons of them since the last upgrade. Will look into them now.

One additional thing to try. You'll need to edit /YOUR_ADMIN/includes/application_top.php, starting at line 31:

/**
 * set the level of error reporting
 *
 * Note STRICT_ERROR_REPORTING should never be set to true on a production site. <br />
 * It is mainly there to show php warnings during testing/bug fixing phases.<br />
 * note for strict error reporting we also turn on show_errors as this may be disabled<br />
 * in php.ini. Otherwise we respect the php.ini setting
 *
 */
if (defined('STRICT_ERROR_REPORTING') && STRICT_ERROR_REPORTING == true) {
  @ini_set('display_errors', TRUE);
  error_reporting(version_compare(PHP_VERSION, 5.3, '>=') ? E_ALL & ~E_DEPRECATED & ~E_NOTICE : version_compare(PHP_VERSION, 5.4, '>=') ? E_ALL & ~E_DEPRECATED & ~E_NOTICE & ~E_STRICT : E_ALL & ~E_NOTICE);
} else {
  error_reporting(0);
}

You'll modify that section to add the line in red:

/**

 *

 * It is mainly there to show php warnings during testing/bug fixing phases.<br />

define ('STRICT_ERROR_REPORTING', true);
if (defined('STRICT_ERROR_REPORTING') && STRICT_ERROR_REPORTING == true) {
  @ini_set('display_errors', TRUE);
  error_reporting(version_compare(PHP_VERSION, 5.3, '>=') ? E_ALL & ~E_DEPRECATED & ~E_NOTICE : version_compare(PHP_VERSION, 5.4, '>=') ? E_ALL & ~E_DEPRECATED & ~E_NOTICE & ~E_STRICT : E_ALL & ~E_NOTICE);
} else {
  error_reporting(0);
}

That might point out a PHP error during the initialization process. Don't forget to either remove that line when you're finished or set the constant to false.
