As the title says, if this: ’ , is in the description, the whole template, gets empty. Tested with all templates. Strangely if you chose no template, all things are in place.
After reading this post (smart forum proposed me too): Invoice Template Bug, i tested and with the notes field and got the same empty invoice, so there must be some " ’ " in bela’s terms and payment advice also.
Everywhere i test it, is the same result
