I just tried to update my signature and the space where it would all go is empty except for some font info.

 

This is what I see:

 

Try logging out then back in, could be just a system fluke.

 

Worked for me.

 

No joy.
Logged out and back in and it is the same.
Literally only the Font tag is in the Edit Signature field.

 

Can either of YOU edit mine?

I was just wanting to remove most of the stupid space between profile pic and the bottom part.

 

Did you try scrolling with the gray bar ? I've edited mine several times before and it's always some weird sequence you have to do.
This is how mine comes up. Notice that the scroll bar is in the middle and doesn't even show the pic that's in there. Until I scroll up.

 

Try FMG’s idea, see if that works

 

I can edit it. Make sure I'm the only one.

 

Is that what you wanted?
