I just followed this tutorial to create a custom new theme for my localhost opencart 2.2 installation. I followed the following instructions from the tutorial :
Let's create a new directory, named mycustomtheme underneath catalog/view/theme. ..... Furthermore, you need to create three more directories within the mycustomtheme directory: image, stylesheet, and templates.
Then I navigated to Admin->System->Settings and clicked on the 'Edit' button of the default store and in the subsequent page expected to get the custom theme in the 'Theme' dropdown but only the 'Default Store theme ' was there.
The tutorial tells that I am supposed to get a 'Template' dropdown there and I found a 'Theme' dropdown instead due to version change I think.
But how to activate the new theme then ?
