Please provide logs, eg: is there any network failure? is there any JS error?

And Gitea 1.16 is RC now, how about trying Gitea 1.16?

Could you try:

1. Use Private Window or clean your browser cache (Ctrl+F5 for Windows browsers)? (to make sure all files are correct)
2. Use 1.16? (if step 1 doesn't help, make sure whether the problem also happens in 1.16)

I just tried it on try.gitea.io (the frontend code is the same as 1.16): https://try.gitea.io/wxiaoguang/test/issues/1 , it works.

My current server is for product. I will try in a new docker container.

I just tried 1.15.10 and can confirm this is a bug in 1.15.10 😭

There isn't important change in 1.15.10 (see the changelog), so you might use 1.15.9 instead, and then 1.16
