I was asked to work on a PDF file - to make some alterations.
However, upon opening the file a window popped up with this message:
An unknown shading type was encountered. An unknown imaging construct was encountered. To preserve appearance, some text has been outlined.
To be sure - when I clicked ok and the file opened, a good part of the text w as covered with pink boxes (I guess these are the outlines) and they didn't get removed even when I saved the file as an "ai" file.
P.S. I added screenshots of the original file and how Illustrator displayed it following
the error message:
