Doing that (after reverting my SMW_Settings.php) results in an error:

Notice: Use of undefined constant NS_BLOG - assumed 'NS_BLOG' in /home/xmm/public_html/w/LocalSettings.php on line 218 Warning: Cannot modify header information - headers already sent by (output started at /home/xmm/public_html/w/LocalSettings.php:218) in /home/xmm/public_html/w/includes/WebResponse.php on line 38 Warning: Cannot modify header information - headers already sent by (output started at /home/xmm/public_html/w/LocalSettings.php:218) in /home/xmm/public_html/w/includes/WebResponse.php on line 38

Any idea why?
