Error upon activating plugin

What does your MCC account data say? Do you have valid account info there or is there an error fetching the data?

If so, see the FAQ on the plugin’s main page.

I can’t check / change / edit anything, as the second I activate the plugin, the website crashes with the above mentioned error.

That’s just a warning and shouldn’t crash anything.

Is WP_DEBUG enabled? Disable that. Is anything else PHP warning related enabed in your webhosting? Disable that also.

WP_DEBUG is disabled (wasn’t enabled before either). There’s nothing else I can disable or check that I haven’t tried yet and besides, I’ve never ever had this happen with any other plugin.

Any ideas as to what I can do?

Complete website crashes usually result in a descriptive error either in the browser, if WP_DEBUG is enabled, or in the webserver’s error log.

I don’t suppose the error log says anything?

Without a real error, and not just the warnings you pasted, it’s difficult for me to say what the problem could be.

I’ve enabled WP_DEBUG and WP_DEBUG_LOG to see what information I can gather.

Upon installing and activating the plugin I get the following error on the Dashboard:

Notice: Undefined property: stdClass::$currency_data in /home/customer/www/websitename/public_html/wp-content/plugins/mycryptocheckout/vendor/mycryptocheckout/api/src/v2/Account.php on line 45

Warning: Invalid argument supplied for foreach() in /home/customer/www/websitename/public_html/wp-content/plugins/mycryptocheckout/src/currencies_trait.php on line 48

And this is the error I get on the live website:

Notice: Undefined property: stdClass::$currency_data in /home/customer/www/websitename/public_html/wp-content/plugins/mycryptocheckout/vendor/mycryptocheckout/api/src/v2/Account.php on line 45

Warning: Invalid argument supplied for foreach() in /home/customer/www/websitename/public_html/wp-content/plugins/mycryptocheckout/src/currencies_trait.php on line 48

Upon going into Settings -> MyCryptoCheckout, I get the following message:

It appears as if MyCryptoCheckout was unable to retrieve your account data from the API server.

Click the Refresh your account data button below to try and retrieve your account data again.

After clicking the “Refresh button”, I get:

2021-06-08 15:03:18

Error refreshing your account data. Please enable debug mode to find the error.

Hope this helps, but if it’s not enough, let me know what else I can provide. Thank you!

Hey! Did you get a chance to look over the logs? Thank you! ??

This is the core of your problem. Our FAQ has a section for this:

Unable to retrieve your account data

If MyCryptoCheckout is unable to retrieve the account data for your domain, it’s usually due to the MCC API server being blocked from connecting to your install. Check for:

Maintenance plugins
Password protection plugins
Firewalls

I’ve just tried everything I could, allowing the MyCryptoCheckout API host on CloudFlare Firewall and all other security features, but to no avail. Anyway, thank you kindly for your time and support, appreciate it!
