Multiple Instances of Enfold

I need to test Enfold 4 before I install it in place of Enfold 3 so need to be able to run two instances of the Enfold theme in a WPMU environment.

I did this my installing Enfold 4 in a new directory (/public_html/wp-content/themes/enfold4) and then changed the Theme Name in style.css to “Enfold 4”.

Everything worked as expected when I changed the theme for my test site to “Enfold 4” but when I set up a child theme under Enfold 4 it did not work as well.

The only changes I made to style.css in the child theme directory were to specify “enfold4-child” as the Text Domain and the @import statement to “./enfold4/style.css”.

But when I specify this child theme as the site theme, the choices “Enfold 2017” and “Enfold Classis” no longer appear in the Theme Options > General Style color scheme grid and “Transparent Header with Border” no longer appears as an option in the page editor.

So my question is…how can I run multiple instances (two) of the Enfold theme under WPMU…??

thank you in advance…
