Good morning
The multiple upload seems to work (alone), but if I add the image resizing, the operation stops. It seems that I can't open the file for resizing and save. All folders (temporary and destination) have read and write permissions.


The sequence of operations is this:


Thank you

Hello Luca,
this is not the right part of the error message.
Can you please email a link to your site to so i can test this?

Hello Teodor, just the time to set up access and forward the credentials

The actual error returned by your server is:

Thanks for the quick reply, Teodor.
I hope to solve

It seems I have the same problem. Al my upload folders has read/write permissions

See topic: https://www.dmxzone.com/support/23308/topic/63250

My remote server is configured as medium trust and can't be changed (Not allowed by the provider).

When I setup my local server as full trust everything works fine.
When I setup my local server to medium trust I get 500 upload errors.

When I chance this with web.config local everything works fine:

<system.web>
  <securityPolicy>
    <trustLevel name="Full" policyFile="internal"/>
  </securityPolicy>
</system.web>

But when uploading this web.config to remote server I get a 500 upload errors

And again to DMXzone I know this is another technic but with the older PAU and SIP I have no problems at all on remote with medium trust
