Fillable fields are gone in Adobe Acrobat Reader DC
I used to fill out pdf forms with fillable fields but now the fillable fields are gone. The fillable form fields used to be highlighted with light blue where I can easily enter the information but one day it just disappeared and the file looks like it's printed already. As I clicked many times the fillable fields, an error message appeared saying "The updater plug-in has been removed. Please re-install Adobe Acrobat to continue viewing the current file". I re-installed the application many times but it did not fix the issue.
Below is the screenshot of the error message. You can see on the form below there are boxes, those are the fillable fields that used to be highlighted with light blue.
Does anyone know how to fix it or can anyone help me?
