not working

Hi,
Let me clear up the timeline first, then give you something concrete to try.

First, some context: the two-year period you describe goes back to the previous CodeCanyon version of the plugin — the WordPress.org release is recent. In all that time I never received a report about this from you. Had you reached out, I would gladly have looked into it, and I still will.

Attaching uploaded files to orders is the plugin’s core function and works on the large majority of installations, so a permanent failure like the one you describe usually points to something specific to a given setup rather than to the plugin itself.

There is one cause I see fairly often: some third-party plugins alter the normal WooCommerce checkout flow, and as a result the upload plugin is never notified that the checkout was completed — so the files are never associated with the order. It works everywhere else, and silently fails on that one site.

In the meantime, here is something concrete you can try right now: go to Settings → “Checkout – Files to order association method” and switch it to the other value. In a good number of cases that alone resolves it.

If it doesn’t, I am genuinely happy to help. Please get in touch through the proper channels — either this support forum, or https://vanquishplugins.com/support/ — with a few details about your setup (a debug log is ideal). With that I can usually pinpoint the cause quickly.

Thanks for the follow-up, and good news that the uploads are working now.

On the remaining point — the box not showing on every product — I need some more clues to be sure about the possible cause. First question: are you using the Free version or the Premium?

Two clarifications, with no polemic intended.

The file-attachment problem — which is what this review is about — is, by your own
account, resolved in the WordPress.org version. That problem belonged to the
previous CodeCanyon plugin, which is a separate product from the one reviewed here.

And regarding the CodeCanyon thread: after some search I found the thread. I did reply at the time, asking you to run a couple of checks and to send temporary access so I could investigate directly on
your installation. I never received an answer, and without that there was little
more support could do.
