问题描述 | Describe the bug

我尝试更新了waline后，waline example页面变为空，但是管理页面（/ui）可以正常使用，管理页面上方的更新横幅也消失了，前端个人博客中可能因为没有更新css所以版本号没变，后端部署网址如下：
comment.qingyang.eu.org
出现错误为：

init.ts:81 TypeError: Cannot read properties of null (reading 'toLowerCase')
    at zo (index.ts:34:46)
    at Po (config.ts:91:9)
    at WalineComment.vue:153:31
    at zr.fn (reactivity.esm-bundler.js:992:13)
    at zr.run (reactivity.esm-bundler.js:176:19)
    at get value (reactivity.esm-bundler.js:1003:61)
    at setup (WalineComment.vue:156:38)

Problem description | Describe the bug

After I tried to update waline, the waline example page became empty, but the management page (/ui) could be used normally, and the update banner above the management page also disappeared. The version number in the front-end personal blog may not have been updated because the css was not updated. The backend deployment URL is as follows:
comment.qingyang.eu.org
The error occurs as:

init.ts:81 TypeError: Cannot read properties of null (reading 'toLowerCase')
    at zo (index.ts:34:46)
    at Po (config.ts:91:9)
    at WalineComment.vue:153:31
