Undefined constant TOPMOST_CATEGORY_PARENT_ID

Dear Friends,

We are currently using Zen Cart 1.5.8 under PHP 8.1.9 Version at www.celextel.com.

We are getting Blank Page when we try to change the Currency in any Product Info Page.

Example URL:
https://www.celextel.com/?currency=INR&main_page=product_info&products_id=76&cPath=5

Debug Log File is showing the following Logs:

[03-Nov-2022 11:08:45 Asia/Kolkata] PHP Fatal error: Uncaught Error: Undefined constant "TOPMOST_CATEGORY_PARENT_ID" in /home/xxxx/public_html/includes/functions/functions_categories.php:186

We have not made changes to any of these Files.

We do not find Configuration Setting for the following in DB:
TOPMOST_CATEGORY_PARENT_ID

Please guide us as to what to do in this regard.

Thanks,

Does this issue go away when you turn off Ultimate SEO URLs?

Yes, you are correct. Pages are seen when Ultimate SEO URLs are disabled.

Okay, thanks.

Thanks scottcwilson for the solution through Pull Request.

First two files of Zen Cart 1.5.8 already has got the code mentioned by you,

Our website with Ultimate SEO URLs enabled is working fine now after adding the code mentioned by you in the following third file:

includes/init_includes/init_non_db_settings.php
// Shared - Storefront and Admin
'TOPMOST_CATEGORY_PARENT_ID' => 0,

Thanks,

Lakshmanan

Thanks for confirming @ Lakshmanan! Added to the 1.5.8 known bug list.
