Agree with Marion. It's not worth the effort and no-right-click plugins just annoy users that want to make legit right clicks (like open a link in a new tab).

It's not worth the effort. If someone is determined to copy your content they can simply copy the source code.

I use
WP Content Copy Protection & No Right Click
It works really well. It will stop them from copy and paste but not alt print screen

Better ask support
The magicians...
