I have been searching the web and there is no clear and easy way found. I was hoping for step by step instructions or a video.
Hi Kurrent,
Go to your Cpanel > Click 'File manager' > YOURSITE/wp-content/themes ( upload your theme folder here). If you face any problem, reply me here.
Is this a paid plugin that can do it?
