Now I'm completely useless with signatures

That’s the phrase at the bottom of your post that’s separated from the post by a line, right?
When I wrote my (first!) sig and then clicked on “Save Signature”, there was no sign of it at the bottom of any of my posts.
No longer using Sultantheme, if that’s got anything to do with it.

User CP>Edit Options>Thread Display Options>checkbox “Show Signatures”

Save changes button at bottom of page.

There are also “show your signature” checkboxes on the Reply and Quick Reply pages.


I see the sig at the bottom of my profile ("about me " section)

I’m guessing one can’t delete it from the profile and use it only for posts?

Only if you insert it in your posts manually.
