Okay, I think this is a misunderstanding. This is a fairly new WP installation, with a fairly new plugin. The directory name on my server is: “advanced-custom-fields-pro”. But when I download this file: advanced-custom-fields-pro.zip, there is a directory called “advanced-custom-fields” inside, without the -pro. I think I cannot overwrite one with the other. I have ACF Pro (Developer license) installed and it’s working fine so far, except the “Update package not available” error.
