After successfully adding my HD wallet for Bitcoin, I attempted to do the same with Bitcoin Cash and received this critical error (I added xxx to hide sensitive information):
WordPress version 6.6.2
Active theme: Shoptimizer (version 2.8.3)
Current plugin: MyCryptoCheckout (version 2.137)
PHP version 7.4.33
