Thanks for your Thanks, and sorry for the untimely response.
It seems that I did mess up my replies! Sorry for that 😀
I see it still says 1.6
I suggest trying the envato WordPress tool kit for the update, It’s faster and more reliable.
Please backup your installation first, along with an export of the DB
and install the plugin https://github.com/envato/envato-wordpress-toolkit/archive/master.zip
then update the theme using the plugin dashboard
