After installing this plugin, I initially went to configure it. The interface seemed to work well until I tried to upload an image. After uploading an image, I was given an acknowledgement that the image was uploaded successfully. But then the configuration menu became stuck in the image upload state, where there appears to be two table headers for images that were uploaded but the tables are empty. It allows me to keep uploading images, and gives me successful acknowledgements, but does not allow me back to the previous setting menu.
I uninstalled the plugin, deleted the files, and then reinstalled the plugin and ran into the same issue.
