Hello,

Thanks for reaching out. I have moved your post its own new thread.

The Coin Adapter extension includes a cron job that continuously attempts to re-create any currencies that you have enabled in CoinPayments. But it should be skipping any already existing currencies.

I have seen this problem before, and it’s hard to track down / reproduce, because it’s a concurrency issue that only occurs on some installations, but fortunately there is a workaround.

First, to make sure, please check the following:

1. Are you running the latest versions of wallets (6.3.1) and the CoinPayments adapter (2.0.8)?
2. Visit _Settings_ -> _Bitcoin and Altcoin Wallets_ -> _Cron tasks_. Do you should see a message telling you to add DISABLE_WP_CRON to your wp-config.php file?

If so, please go ahead and apply this edit to wp-config.php. This will disable the default trigerring of cron tasks by WordPress.

The message will change to notify you that WP CRON is disabled and that you need to trigger crons manually.

You should then set up some external cron that will hit /wp-cron.php on your site, once every minute. This has an added benefit: It will also improve the site’s performance, since transaction processing will no longer happen on user HTTP requests.

Your cron entry should look something like this:

* * * * * curl -Lk https://example.com/wp-cron.php

You should be able to do this either via Cpanel, or with EasyCron or from another server that you control. Let me know if you need help.

Once you switch the cron tasks to external triggering, the problem should not occur again.

Finally, delete any currencies that are not used, and only leave the ones that already have transactions, if any.

Hope this helps. Please let me know if you encounter any more problems or if you have any questions.

with regards,
Alex

Thanks for your quick response, Alex,
Yes, I am running the latest versions of wallets (6.3.1) and the CoinPayments adapter (2.0.8)
This is a local web server in beta stage behind regular home router so I will fwd 80/443 traffic to my webserver to be able to use external cron that will hit /wp-cron.php.
I will apply and get respond back once solved.

Thanks again 🙂

Hello,
Since you are running on a local web server, you don’t have to forward any ports, you can simply trigger /wp-cron.php from your local machine.
Let me know if you encounter any problems.
