Page source: <meta name="lightning" content="lnurlp:morkam4.dreamhosters.com/wp-json/lnp-alby/v1/lnurlp" /></head>

morkam4.dreamhosters.com/wp-json/lnp-alby/v1/lnurlp

leads to {"status":"OK","callback":"https:\/\/morkam4.dreamhosters.com\/wp-json\/lnp-alby\/v1\/lnurlp\/callback","minSendable":10000,"maxSendable":1000000000,"tag":"payRequest","commentAllowed":128,"payerData":{"name":{"mandatory":false}},"metadata":"[[\"text\\\/identifier\",\"https:\\\/\\\/morkam4.dreamhosters.com\"],[\"text\\\/plain\",\"Just another WordPress site\"]]"}

https://morkam4.dreamhosters.com//wp-json//lnp-alby//v1//lnurlp//callback adding ?amount=10000 to https://morkam4.dreamhosters.com//wp-json//lnp-alby//v1//lnurlp//callback manually gives {"code":"rest_no_route","message":"No route was found matching the URL and request method.","data":{"status":404}}

if I change it to https://morkam4.dreamhosters.com//index.php//wp-json//lnp-alby//v1//lnurlp//callback I get an invoice which I can pay manually.
