We are using Sitefinity 6.3 (but this also happens on 7.0)
On our development machines, staging server and any other server for that matter, everything works fine. When we move to our cloud hosted live system, everything EXCEPCT the image/video up loader works.
we can "add an image" i.e. it adds the name, a placeholder, but no data is actually uploaded.
Of "e.response is undefinedLine 2259"
It looks to me that there is a problem actually uploading data :(
We have spoken to our hosting provider, and to Telerick, we have followed every how to guide available, but still no resolution. If someone else has experienced this, any advice would be massively appreciated.
