Hi, i need help to disable a permission on my forum, so the users can edit the comments posted on their profile from other users, how can i disable this permission?

@EmaxDev  Members shouldn't be able to edit other member's comments unless you've put them in a moderator or administrator group.  The only option they have is to delete comments made by other members, which is intended since it is their status update.  It only makes sense for them to have the ability to remove comments they do not like/want associated with them, their updates, or their profile.  Think of Facebook.

If they are moderators, you would need to uncheck the 'Edit All Content' permission from the moderation group permissions page in the ACP.
