Signature Issue

Hi there,
I previously had a signature in my e-mails but all of a sudden it’s gone. 
I’ve gone through the process of adding it again in settings --> templates/signatures, etc. but every time I go to compose a new e-mail there is nothing there.

Do you have the account you are sending the mail from setup with the default signature?

Go to menu/tools/settings/mail/templates and signatures

I doooo :( 

Is your signature a graphic or text?  If a graphic, make sure that you are configured to compose in HTML-- menu/tools/settings/mail/compose.  In the mail format section make sure HTML is selected as the new mail format.

you’re my hero!!! thank you SO much!
