The code for the sidebar is:

skin_container( NT_('Sidebar'), array(
// The following (optional) params will be used as defaults for widgets included in this container:
// This will enclose each widget in a block:
'block_start' => '<div class="evo_side_item $wi_class$">',
'block_end' => '</div>',
// This will enclose the title of each widget:
'block_title_start' => '<h3>',
'block_title_end' => '</h3>',
// If a widget displays a list, this will enclose that list:
'list_start' => '<ul>',
'list_end' => '</ul>',
// This will enclose each item in a list:
'item_start' => '<li>',
'item_end' => '</li>',
// This will enclose sub-lists in a list:
'group_start' => '<ul>',
'group_end' => '</ul>',
) );


Just replace NT_(’Sidebar’) with NT_(’Sidebar 2′) if you want to make use of a second sidebar (this allows you to add widgets to a second sidebar).

HTH.

do you know how to recover an accidentally deleted sidebar container from b2evo?
as you mentioned above, i had the same issue, but removed all of the widgets before
thinking about adding the sidebar. i tried it on another blog and sidebar works but
on my main blog there is noe more container.. reloading does not help

help is appreciated

thanks & cheers phk
