When there are errors with namecheap hosts, acme.sh fails with: dns_namecheap.sh: line 262: _error: command not found Based on usage elsewhere in the file, I believe this should be _err
URL https://ipconfig.co/ip does not currently work, and since https://ifconfig.co/ip is mentioned on the DNS API wiki page, I assume these messages were a typo.
This issue in the shell scripts will also be detected in the stable version of shfmt(we are currently using an ancient pre-release of shfmt)
