I installede Treeview4.php in the directory indicated and edited the LocalSetting.php to include the following:
############################################################### ##added by jwf 02/25/08 to install Treeiew4 include("$IP/extensions/Treeview4.php"); $wgTreeViewImages['plus'] = "Plus.gif"; $wgTreeViewImages['minus'] = "Minus.gif"; $wgTreeViewImages['opened'] = "Folder_opn_sml_yel.gif"; $wgTreeViewImages['closed'] = "Folder_sml_yel.gif"; $wgTreeViewImages['doc'] = "Doc-icon.gif"; $wgTreeViewImages['spacer'] = "Blank.gif";
Now I get this message:
Warning: Cannot modify header information - headers already sent by (output started at /var/lib/mediawiki/extensions/Treeview4.php:246) in /usr/share/mediawiki/includes/WebResponse.php on line 10
This seems to happen with a lot of extensions and only goes away when I remove the extension. The install is to the letter what is supposed to be done per the author. Can anyone tell me what the problem is? Oh yeh: the extension does not work either. Thanks!!\ frosty
