Signatures issue

[marengo]

Hi,

Admin settings: Users can use signature checked.

I created a signature, enabled it in the profile settings, posted something, seems OK. I added a new reply, no signature visible.

I logout, logged in as a different user and see all signatures.

Logout, logged it again as an user with a signature, seems good.

Posted a new thread: I see all my previous posts with a signature, and the new one - without.

I clear the cache (browser's cache), works again.

In several hours the problem returned again.



Clear System Cache - > all signatures work again, then in some time everything repeats.

Any ideas how to fix it?

Thanks,
Nat
