I submitted a paper to a journal and they couldnâ€™t upload it in to their system because of digital signature. They see a non-validated digial signature on the word document that is preventing them to put into their database. They tried to delete the digital signature but without success. I opened the word file on two different computers and there are no signatures attached to the document that I can see when I use office button>>Prepare option. Is there any other way to remove the digital signature? Please help...thanks so much.
