Unable to attach sample files.
I am trying to ask a question in this forum, and provide the sample files, both generated in Illustrator, but when I want to attach them, again and again I get this sign in the red frame...
I really do not know what it refers to, because in the InDesign forum, I was able to attach sample files generated in InDesign, but it does not allow me to attach the illustrator files here.
I attach the screenshot where can be seen that the files are from illustrator, and that it is their extension.
What is the error here?
Thank you.
