I am working on a document and sent it through an email to others. Afterwards, when I opened it, I haven't been able to edit the document in any way. It is a premade document that I filled in partially, but now I am unable to change anything I wrote or write in it further. I've tried making copies of the document and opening it multiple ways. I've previously had problems changing, deleting, and adding numbers into a premade chart after clicking out of the box. What can I do to make the edits work?
What kind of document are you working on and with what application? Keep in mind, Adobe is just the name of a company, that distributes dozenz of different applications and services. Also, "document" is a general term such as "car", its quite imprecise.
