Here are some further observations to this thread
. (I work with Rob)
If I upload one image I can do so successfully.
If I try to upload multiple images (either to an existing library, or a new one) I get popup windows with the row not found error as posted in the other thread.
After the popup message, the upload will never finish, and I need to click "back to images" to abort the upload.
Once one upload has been aborted, I cannot upload any further images, even one at a time - no error message, the progress bar just keeps spinning forever.
If I restart Sitefinity (by refreshing the web.config file) I can upload one at a time again.
This is driving us nuts - can you please offer a solution? Based on the already painful slowness of working in the backend, uploading one image at a time is not a feasible solution for the size of site we are creating.
Note: We are using SF 5.0 (recently upgraded), and we are using the trial version right now as our site does not have a domain name yet.
