drag and drop error

Hi,
It may be caused by some plugin which disables RightClick option on your pages or posts. It is recommended to disable it. You can try to deactivate plugins one by one to see what exactly caused an issue.
If nothing is helpful you can submit a request and we’ll test it for you.

Hi,
When you add image it stretches it to content width but your image size is not so big to be stretched to cull content width of the page or post. You can simply resize it by putting another element next to the image or simply with your mouse.

It would be helpful if you also provide screenshot of the image properties in Media Library. Or you can submit a request to our support and we’ll have a look at it.
