Snap Affiliates v2.0 for v1.5.0 and later

[Shop Suey]

I have the issue the new points don't show up at the admin.

I'm using the German zen cart version 1.5.7h with PHP 8.2.29 and there is no available plugin available for it.
I was aware it maybe wouldn't work but wanted to give it a chance because the code base should match for the v4.2.0 version of Snap

What I have done:
I renamed the two template folders and the admin folder, copied over the files, merged /includes/templates/responsive_classic/templates/tpl_account_default.php adding the section inbetween lat9 BOF and EOF.

Nothing new shows up at the admin
At first load of the admin I got a white screen and a log file:

[06-Aug-2025 09:12:57 Europe/Berlin] PHP Fatal error: Uncaught Error: Undefined constant "TEXT_SNAP_INSTALLED" in /admin/includes/init_includes/init_snap_admin.php:264

#4 {main}

I understand you can't give support to the German zen cart version but maybe there could be a quick fix

That language-constant is present in the YOUR_ADMIN/includes/languages/extra_definitions/referrers_info.php. Perhaps copying the plugin's language files to the german-language directory will help.

I had copied over from english/ to german/ for not being fooled by myself having the admin language set to a language without plugin language files (German is set as default).
I guess I copied over after I got the blank page, the Log and no entries unter Configuration and Customers.

I will double-check everything again properly.

The German version has all the English language files from the US version. It additionally brings an integration of the German language as default and other optimizations very useful for Europe citizens in terms of legal regulations - amongst other plugins preconfigured and well maintained by webchills.

The missing language definitions could have created this Log.

But the there are no new points under Configuration and Customers.

I double-checked everything.
The installation is pretty straight forward especially for the admin.

I checked manually folder by folder e.g. for observer, refferer, init and so on. It's all there.

The entries e.g. under Configuration just don't appear and I don't know why they aren't picked up into the admin.
