Most of your templates use slider revolution. However when I tried uploading an hero image, JPEG, under 2mb, it gave an HTTP error. I don’t know what an HTTP error means as it doesn’t explain. However it works for some images (uploading fine) but not others.
I tried deactivating all the plugins and tried again, still didn’t work. Any ideas?
Sorry to hear of the problem you are having.
