@no said:
https://femboy.fan/comments?group_by=comment is fine, https://femboy.fan/comments?group_by=post is broken

Hmm, it works elsewhere, did my browser cache an error
Do you keep log ids

Actually it seems to be related to my account
Wait, might it be the test comment (which is considered latest comment) i hid under reggie

I found out the problem. If I have show own hidden comments turned off, it activates the error; if i have it on, there's no problem. Guest users have no problems with my hidden comments, just me

This looks like it should be an upstream issue, the same code that's triggering the issue here is present there
I have no idea where they are on deployments so the bad code may just not have been deployed yet

Oh, I completely skipped over that the setting needs to be off, this is in fact an upstream issue
I've put in a patch for us and will tell them about it
