我按照waline的快速上手文档在github pages上部署好了，在vercel的demo上是可以正常评论的，但是在github pages上打开会报CORS跨域访问问题，下面是chrome浏览器的报错信息。请问除了绑定自定义域名外，是否有其他解决方法？

If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Describe the bug | Problem description

I deployed it on github pages according to waline's Quick Start document, and in vercel's [demo](https://waline-ao2gukw9r- Comments can be made normally on ganyuooutlookcoms-projects.vercel.app/), but when opened on github pages, a CORS cross-domain access problem will be reported. The following is the error message of the Chrome browser. In addition to binding a custom domain name, are there any other solutions?

serverURL 填错了，你现在填的是 vercel 某次部署的预览地址，需要填项目的固定地址，自己在首页找找吧。

The serverURL is filled in incorrectly. What you are filling in now is the preview address of a certain vercel deployment. You need to fill in the fixed address of the project. Find it on the homepage.

修改serverURL后正常了，非常感谢！
