If "define('SMW_HALO_VERSION',true);" doesn't help, I found a solution to fix the bug " Undefined index: riched_load_semantic_toolbar in... "

Delete (or put comment //) these 3 lines in file CKeditor.body.php (line 436)

if ( $wgUser->getOption( 'riched_load_semantic_toolbar', $wgDefaultUserOptions['riched_load_semantic_toolbar'] ) ) { $this->loadSTBonStartup = 1; }

Hope this helps.
