The plugin breaks with most themes, but not all, when assigning a theme to s specific category
Catchable fatal error: Object of class WP_Post could not be converted to string in /home/user/public_html/example.com/wp-content/plugins/wp-subdomains-revisited/plugin/filters.php on line 124
This is the setting on the category page.
"Themes ... You have to activate Subdomain Themes in Settings"
Also, not as big of an issue, but when you select the "Make as subdomain" setting and then save the page, it appears to automatically select the "Exclude as subdomain" every time (so I have to deselect each time I am saving).
Otherwise, awesome plugin
