My members had been adding things like quotes to their signature field. These quotes wrapped into multiple lines and presented fine. I just changed themes and the signature box now only has one line of text and any text longer than the width of the signature box doesn’t show anymore. Anyway to get the lines wrapping and the box expanding in height to accommodate? I tried changing the Signature Image Size incrementally up to 300px but that didn’t increase the box size at all. Any suggestions? 
Thanks for your help.
