Hi Rattus,
sorry but that’s not possible. If you can send me some troubleshooting hints then I can have a look by myself and send you the information you would look for.
I get the same error message.
I have the latest version 3.20 installed and using the same way to prepare my images before it stopped working.
The single browser uploader works but I have to upload lots of files and do it one by one is not really an option.
Any help would be much appreciated.
