I'm having the following issue since the very first version of Membership Pro I installed up to the latest version 1.70.
My website accepts subscriptions both with online payments method (PayPal) and offline method. When a user subscribes and decides to pay with an offline method (i.e. a wire transfer) I ask him to attach a copy of the payment receipt to the subscription form. To that purpose I've set a file type field (a button) in the Membership Pro form that allows the upload of .jpg files.
Everything works fine as long as the user is subscribing for the first time: I go to his profile and find the download link to the document he sent.
However, when the member wants to RENEW his subscription using the same offline method, he gets an error from the website after uploading the payment receipt. The error is: "Warning: failed to move file!".
If I go to the upload folder (in my case it's: /content/media/com_osmembership/upload) I can locate the uploaded file so the upload didn't actually fail, but because of the error the user is lead to think that the file transfer failed, so he tries again and / or contacts out customer service to complain about the failed operation...
I already checked the folder permissions and every other parameter that I could think of, so my question now is: from a technical point of view what does it change between the first time subscription form and the renewal form? As far as I can see it's exactly the same form, so how come this issue only appears in the renewal form?
I need to fix this thing urgently as it's causing lots of troubles to me and it's an annoyance to my subscribers.
