Question:
I run multiple sites in EE. How can I give each of those a different member template theme?
Answer:
Open up your config.php file and find the $conf[‘member_theme’] preference. Remove it from your config.php file and save.
Open up the path.php files for your two sites, put that preference in there and define the names of your member themes. Save.
Caveat: The only thing you have to look out for is that if you edit the Template Preferences, then the original preference will be put back into the config.php file automatically. That will promptly override the path.php setting.
NOTE: Make sure you have a backup copy of your config.php file as well as your path.php file(s) before making a change.
