Sorry if this isn't the right place to ask this question but I couldn't find an answer anywhere else.
I am having a weird problem when trying to transfer pages between two different sites using the tutorial above. When I first tried I was given the copy/paste option in the site menu but when I opened the second site to paste I didn't get these options. Instead I just got a regular right-click menu. Now anytime I try to right click on any site/page I don't get the copy/paste options at all. I tried all the troubleshooting options (clearing cache, flushing DNS, restarting, using a different browser) but nothing has worked.
I also tried just copying only certain elements but it's the same. I can copy but I don't get the option to paste.
I don't know why it gave me the option once and then not again.
