Search ok, register not working

I have loaded a few screenshots to a google slide documnet which shows the problem. in short, i don’t have the plugin working [ie registering images to media library] – no confirmation and no chance to look at log – it is empty.

i am using hostgator to host the site.

help much appreciated.
