Thread:Project:Support desk/Problems mediawiki version 1.20 and WikiEditor

Hello. I installed mediawiki version 1.20 with WikiEditor extension but the extension does not appear when I try to edit web pages. I've tried installing other editors like fckeditor and does not appear when editing the web. Would this happen to anyone else?

The versions of php and mysql are: MySQL 5.5.27 PHP 5.4.7

I checked the lines and are LocalSetting.php: require_once( "$IP/extensions/WikiEditor/WikiEditor.php" );
 * 1) The following extensions were automatically enabled:

thanks
