blank pages when upgrading to 2.10 zencart - unusual time stamp error logs

[HeathenMagic]

php 8.2 , tried php 8.3 also. Zencart 2.10

I wonder if someone might know what is causing these logs at all please? I am getting blank page on admin and store, it seems to be just the following error log. I had similar error when upgrading the dev site from 2.01, and did the 2.10 update carefully. Either I have done something really stupid or its a server related issue. I do recall having to do a fix for time / date at a previous upgrade juncture as I found a few others at that time having the same error. But I tried searching for some of these error warning snippets, but no results. Thanks in advance.

Have a look at the top of that file "/home/t**/public_html/test_store************/includes/init_includes/init_errors.php" ("\admin\includes\init_includes\init_errors.php").

Line 6 should read " * @version $Id: torvista 2022 Mar 01 Modified in v1.5.8-alpha $" .
This latest file has "coupon_expire_date" on line 158
whereas the zc157 version has "coupon_expire_date" on line 158

Thanks for reply. Yes I had one line difference around there which seems to have pushed the line numbers around as you spotted. It was the following:-

define('NEW_SIGNUP_DISCOUNT_COUPON', 'New Signup Discount'); 

Which I saw was not in 2.10 so I overwrote. Though I get a second log now as follows:-

--> PHP Fatal error: Uncaught Error: Undefined constant "NEW_SIGNUP_DISCOUNT_COUPON" in 

[lat9]

You've configured a NEW_SIGNUP_DISCOUNT_COUPON (Configuration / GV COUPONS / New Signup Discount Coupon ID#) that no longer exists.

If you have access to your cPanel phpMyAdmin, you can search the site's configuration table's configuration_key fields for NEW_SIGNUP_DISCOUNT_COUPON and change that to 0.

You could also create a simple file in the admin/includes/extra_datafiles/set_new_signup_discount_coupon.php that contains

<?php
define('NEW_SIGNUP_DISCOUNT_COUPON', '0');

Once you've successfully logged in, navigate to Configuration / GV Coupons to change that value and remove the newly-added file.

Thanks for that! I actually searched for it and could not find, so I managed to add that sql line (via phpmyadmin) and an associated one and it seems those logs disappear. I can see admin login now, but live site still blank. I suppose my only recourse is to try the application_bootstrap.php and enable the relevant debug tester to 'true' and see what I can find? This 2.10 dev site is from the 1.58a path, where I did have to remove old defines that were giving possible blanks. But can't be that I suppose as already fixed them, Not getting any other error logs right now, just deprecated I think and they I reckon don't pose a problem just yet?

[HeathenMagic]

Ah I just realised this tool:-

if (!defined('DEBUG_AUTOLOAD')) define('DEBUG_AUTOLOAD', false);

Is for admin side only I think, I tried developers toolkit to see if it occurs in includes/ . For 1.58a I had blank admin page for so long so this was useful for that, typical I have it other way round now lol.

Though the only log I got since is starting like below, but it mentions debug so must have been when I was trying debu_autoload:-

--> PHP Warning: Cannot modify header information - headers already sent by (output started at /home/*********/public_html/********/includes/classes/InitSystem.php:58) in /home/***********/public_html/********/includes/init_includes/init_gzip.php on line 34. 

[HeathenMagic]

Actually looking at deprecated log, there is a fatal one there. Thats a lesson learned not to overlook them I guess!

Its a weird one, I actually replaced this modified file (2.10 template supported apparently) and still blank, but perhaps somewhere for me to work from:-

PHP Fatal error:  Uncaught TypeError: Unsupported operand types: string + string in /home/*****/****/includes/templates/****/common/tpl_main_page.php:81
Stack trace:
#0 /home/*****/***/****/index.php(94): require()
#1 {main}
  thrown in /home/*****/public_html/***/includes/templates/****/common/tpl_main_page.php on line 81 

Which seems to be the following:-

$side_columns_total = $box_width_left + $box_width_right; 

I guess it could be a sql issue similar to the discount coupon thing?

[HeathenMagic]

Think I am getting there now! Yes it must have been a php thing recognising this value, I have actually had pre 1.58a so must be stricter rules in the php language now:-


Column Width - Right = Auto

So I changed to a 250 px (though in template I turned off sideboxes right usually)

And I am seeing a bit more progress on live site, something else to fix but deprecated error logs giving me clear pointers now. Think its just a sql entry from 2.10 update somehow needs adding again, somehow it must have not passed through in phpmyadmin (was doing it that way because of blank status).
