I have marked this extension as Incompatible with the latest Flarum release 1.8. If this changes feel free to report it back so the moderation staff can get back to it.

    @cxm This is great extension. please take a look at it. i had it for long time and so sad that it's incompatible with 1.8

      May I ask what is the issue you encountered in v1.8? My issue is that after posting a reply-to-see post, the hidden box will only be displayed after someone replies once, then the reply-to-see function can work normally. However, when I tested the code, I found it had been replaced according to regex, but still could not be displayed. Oh my god, who can save it?

        GreXXL It seems that it is work on v1.8.2. I am using that.
