I downloaded this theme from wordpress:


If I want to install it, I am getting always the following error:

The parent theme could not be found. You will need to install the parent theme, isola-wpcom, before you can use this child theme.

I already tried to install the theme "Isola" but that don't help. Searching for "isola-wpcom" on google also gave me no results.

Does anybody has an idea? Thank you for your support.

I think you need this: https://wordpress.org/themes/isola/

Really simple some themes do have some requirements, either other themes or plugins. However, after some checking, I cannot find the theme "celsius".

If we check the source code from https://celsiusdemo.wordpress.com/ And precisely the style.css you will get the feedback the theme name is Isola.

  • First, thanky you for your answer. Unfortunately, like I've written above, is the theme "Isola" already installed and activated, but the installation-error with the orther theme "celsius" remains the same. Do you have any other ideas? I think the problem is the missing "-wpcom" ending...
