OK, nevermind, it doesn’t matter where the shortcode is.
I looked at the JSON API endpoint: http://tgtrade.com.ng/?__wallets_apiversion=3&__wallets_action=get_coins_info
and the response looks as if I’m not logged in.
This means that some server-side cache is caching the JSON API responses.
If you know of any such cache that you’re using, you must add an exclusion (white list) for any URLs that have the
__wallets_action GET parameter.
Let me know if you can’t find this.
