I inherited a site where the previous developer created a files folder on the drupal installation level for the live site and set the drupal path in the file system to files. I created a sandbox site to do testing on and copied over the files from the live site. At first, I was getting that error "The selected file /tmp/[filename] could not be uploaded, because the destination files/rotor/[filename] is not properly configured." when I tried to upload an image using the rotor item content type. Apparently this module creates a rotor folder within whatever the folder is that is specified in the file system settings. To resolve this, I was able to go in the file manager on cpanel, rename the rotor folder to another name, then perform the upload again. This time it was successful as a new rotor folder was created automatically.
The problem now is that I cannot copy the files that were in the original folder back into the new folder because I get a permission denied error. The folder permissions are set to 775. Now I will have to reload each image individually.
I don't whether to label this a bug or not but it has certainly been frustrating. Anyone else had this experience ??
