Another theme prob

[Connie]

first, welcome here!

It is good that you found the way to our forum here.

I can say that only template.php is necessary, if you link to another CSS in your template, that is ok

GS will identify all .php-files in the themes folder and will set template.php as default-template when you open the options of a page

the question is:

how you installed the theme.
And which theme.
And if you can show us the URL

maybe you set the wrong URL in the settings? That could be one of the reasons why the theme is not found.

what's the result of the server - health - check? (Settings - first steps - server health check)

Cheers, Connie
