I have downloaded 4.6.4 but cannot upload this into WordPress. Error is folder already exists. How should I upload the latest version? Do I need to uninstall the current one (4.3.0) and then reinstall 4.6.4? I am also unable to update my homepage so am assuming installing the latest version will solve this. Am I correct?
Thanks for writing in! Instead to installing the theme you should update the theme via WordPress automatic updater. To do this go to Dashboard > Updates and scroll down to the Theme section, you should be able to see the X theme update if your theme is validated. Just select X theme and update it to the latest version.
