A user in my forum asked me a question and I don’t know the answer, so I’m asking here: **Why can the user remove some of their messages and some not?** The user gave me examples of both, and I checked. It was true. I think the difference was this: **The user could remove posts in a locked topic, but not in an open topic.** ---

They can’t remove topics, only normal replies. So if it is the first post, they can’t. ---

Both of the posts the user could/could not remove were replies (posts), not original topic posts. Edit: oh, and there was also different category with slightly different security rules: category 1: everyone can see, tl0 read/write/reply, user could remove in locked thread category 2: everyone can see, tl1 read/write/reply, user could not remove in locked thread ---

An archived topic prevents all actions. Other than that, and the first post, I can’t think of any reason. ---

Another thing to check is the `post edit time limit`, as I believe the user has to be in that window of time for them to be able to delete the post. ---

This was the solution! I didn’t know that setting existed and affected editing and/or removing posts. ---

Oh was this a very old message? Worth mentioning 😉 The default is 3 months, I believe. ---

I realised it after @cpradio’s message. I think default is 60 days. ---

Yes, it is `post edit time limit` which is 86400 or 60 x 24 x 60 .. so you’re correct, 60 days. ---
