Thank you for providing screenshots. Unfortunately I was not able to determine what the issue is.
Just to make sure that we are on the same page, I will summarise the issue so far. Please check that I have understood you correctly.
The plugin is not being notified immediately about incoming deposits.
You have added the following lines to your config file:
walletnotify=curl -s 'https://exchange.napocoin.net/wp-json/dswallets/v1/walletnotify/25335/%s' >/dev/null
blocknotify=curl -s 'https://exchange.napocoin.net/wp-json/dswallets/v1/blocknotify/25335/%s' >/dev/null
Where 25335 is the post_id of your Napocoin Currency entry.
When you logged in to your wallet server, you have attempted the following command:
curl ‘https://exchange.napocoin.net/wp-json/dswallets/v1/walletnotify/25335/ABCD’
and you get as result:
{"message":"The plugin is being notified about this TXID. If a user is associated with one of its output addresses, a deposit will be registered for this user.","status":"success"}
The above is to be expected when the TXID is invalid.
But if you try the same command with a correct TXID that corresponds to your deposit, then you see on the screen the message:
There has been a critical error on this website.
This may be due to a difference between napocoin and bitcoin JSON-RPC APIs. The difference could be something trivial.
The only way to be sure is to see the PHP error that occurs at the time when you run the curl command with the correct TXID.
Can you please find this error message? The error will be in your PHP error log, and also in wp-content/debug.log if logging is enabled.
Let me know if you can find the error.
with regards
