How can I make my signature to show up?

[Vicissitudo]

I hope it's the right place where to post this, I've searched a "General Help" subforum but I couldn't find anything.

However, my signature's text length is within limits. I've done everything following the instructions but it won't show up. There is no image attached.
I've also tried by changing it with even a single-word-signature but it won't show up in my posts.

Can anyone explain me what I'm missing?

Thank you in advance!

/edit

Now works...well that's awkward! Thanks anyway!
