Sorry, but i can not figure out how i can upload a picture to my post.
I always get this message:
"Error

You failed to complete the form correctly, please return to the previous page and try again."

Thanks,

Hi @SLX. Do you mean a forum post?

Can you quickly outline to me the steps you are taking to upload a picture?
