Theme is not appearing in Appearance for multi site in Drupal 7

Question

I am using Drupal 7 and trying to make multisite using same database, For this i am using Domain Access and Domain Theme modules. For my default site I am using /sites/all folder theme and module and for another site i have created a folder in the location /sites/example.com and also create a Module and Theme folder and setting.php into that example.com folder and place the theme & module for the relevant folder.

Now the theme which i put into that directory /sites/example.com/themes is not appearing into the Appearance section from back end for the main site. And for the domain site it is showing into the Appearance section. When i enable that theme for the domain site it enabled but after refreshing the main site its again disable for the domain site.

For this condition i did not find that theme into domain theme setting section .And if i go to the Setting of the Home/Administration/Appearance section and select that example theme it showing the following error.

Notice: Undefined index: example in system_theme_settings() (line 404 of /modules/system/system.admin.inc).

Notice: Trying to get property of non-object in system_theme_settings() (line 404 of /modules/system/system.admin.inc).

Can anyone please tell me how can i resolve this theme issue for create a multi-site in Drupal 7 using Domain theme and Domain access module??

Couple things to look for:

• Does your theme require a parent theme, or an engine, that might not be enabled?
• Have you cleared the site cache since installing the theme?
