Sticky Why are all my users able to delete and edit other users' messages on my forum?

Hi, I have been searching at your forum how to customize the buttons to be displayed according to the user profile. That is, for an administrator user profile I wanto to show all the buttons, but for a common user I only want to show some buttons. Please see the attached image. The question is: How can I configure this buttons ?.

Thanks,

G'day, Franco, and welcome to Kunena.

I'm sorry. I do not understand what you want to "customise"; your image is missing.

Hi, thanks for answer.
My question is: How to disable at the topic some buttons like "Edit", "Delete", "Lock" or "Moderate" for certain users ?.
For example I don't want that anybody can delete any topic.
As you are doing in this forum, you only have buttons for "Replay Topic", "Unsuscribe", "Favorite", "Threaded", "Indented", "Reply", "Quote" and "Edit" only for the author.
I was trying to upload an image in order to explain my problem but the upload is cancelled.
Any help will be greatly appreciated.

Thanks,

If you don't want users edit their post, just go to Kunena backend > Forum Configuration > [tab] Users > User Edits: Set to NO

Hi, the "User Edit" option at "Forum Configuration" is to "Set to Yes to allow registered users to edit their own posts.".
My problem is other, I don't want that a user be able to delete the topic of other user. I want that a user be able to post, subscribe, say thanks, edit only your own topics but not to edit or delete topics from other users.
In the same way we are doing in this forum.
Any help will be greatly appreciated.

Thanks,

But that only administrators or moderators can see, not seen by ordinary users!!!
