Forum OpenACS Q&A: Cannot change Portlet themes ;(

I have a problem with using my own portlet theme.

These are the steps i did so far:

1. Create a new entry in the portal_element_themes table for the new theme:

   Insert
   into   portal_element_themes
   values (
           (
            select max(theme_id)+1 from portal_element_themes
           ),
           ' #new-portal.mannheim_theme_name# ',
           ' #new-portal.mannheim_theme_description# ',
           'themes/mannheim’,
           'themes/mannheim'
          );
   

2. Translate the tokens for different locales using the toggle translator mode
3. Create Corresponding files inside the new-portal package under

   /www/unima0/packages/new-portal/www/themes
   File: mannheim-theme.adp
   Folder: mannheim-theme/
   

4. Change the ACS Parameter

   -->Site-Map:New Portal Package parameter:
   default_theme_name	#new-portal.mannheim_theme_name#
   

5. Change the settings under .LRN Site Wide Admininistration --> Portal Templates for Communities, My Space, Subgroups, Classes to the new theme.

But it still doesn't show when I go to My Space.

Can anybody tell me what goes wrong here?
