Hello, I followed the instruction and installed the flash.php extension. I also added a line like this in my page: <swf width="400" height="90">http://testwww. . . /4wiki.swf</swf>, but I am getting this error: Warning: Cannot modify header information - headers already sent by (output started at /var/www/apache2-default/wiki/extensions/flash.php:105) in /var/www/apache2-default/wiki/includes/WebResponse.php on line 10 I am using this extension available at http://www.mediawiki.org/wiki/Extension:Flash_Extension : <?php // MediaWiki Swf Extension Ver 0.1 // Set up MediaWiki to react to the "<swf>" tag // Original file by Brigitte Jellinek // Modified by Daniel Mustieles Can this problem be fixed? If yes, how? Thanks for your help in advance!
