Clone Skin Not working
Using Jamroom
Can you go to:
ACP -> MODULES -> CORE -> SYSTEM CORE -> TOOLS -> SYSTEM CHECK
and see if there are any orange dots on any of the requirements please.
Then run an integrity check
ACP -> MODULES -> CORE -> TOOLS -> INTEGRITY CHECK -> (check all the checkboxes)
If it still doesn't work, open the developer tools of your browser (probably by pushing F12 on the keyboard) and navigate to the CONSOLE tab and see if any errors show there when you try to clone the skin.
