I've read a lot about this issue and tried many things but can't get the result I want - to change the default twentyeleven theme.
I've put this line in wp-config, with the theme folder I want:
I get a blank page.
Tried also to change the names of the themes in their stylesheets, their folder names. To change the default theme in default-constants.php. Nothing works.
I am working with subdomains if that's important to mention.
I have a network of 50 sites and want to change all themes at once.
Advice will be appreciated! :)
