Order Files Upload for Virtuemart not working

We have an issue with the picture that the user is uploading on the product page. The user can upload the picture but at the next step, the cart details, the picture is not displayed, not even on the invoice.

Can you please check the link: ambaesthetics.co.uk/cardsproj4/index.php...&Itemid=1105&lang=en

virtuemart version: 3.8.4

Thank You

Hi Alin,
Please create a support ticket and share your admin & FTP login credentials in it. We'll check it thoroughly.

Hello. I also have the same problem. My upload is not working at all.
When I upload the file it says ERROR: Internal Server Error
VirtueMart 3.8.4 10335

Hi John,
Apologies for inconvenience!

Please create support a ticket and share admin & FTP login credentials in it.

I have already done this.
However, you ask from everyone login and ftp details. This is very unusual way of solving the problems of this kind.
Some people cannot give access to their server for security reasons.
Plugin obviously have problem on certain servers. If you solve the problem once and post it here then it would be easier for everyone who payed for your plugin.
I have already opened support ticket but for FTP and admin access I can offer you Teamviewer or Anydesk remote control so we can solve this problem together.
In my report there is 500 server error which means your plugin don't handle the things good.
