   I'm having ver frequently on my error log this error

   PHP Notice: Undefined index: HTTP_ACCEPT_ENCODING in /var/www/vhosts/mysite.com/httpdocs/wp-includes/js/tinymce/wp-tinymce.php on line 23, referer: http://mysite.com/wp-admin/post.php?action=edit&post=32352&message=1

   do you have any cache plugins installed?

   that looks to be related to gzip encoding.

   you could just remove or comment out this stuff inside the files:

   if ( isset($_GET['c']) && 1 == $_GET['c'] && false !== strpos( strtolower($_SERVER['HTTP_ACCEPT_ENCODING']), 'gzip') && ( $file = get_file($basepath . '/wp-tinymce.js.gz') ) ) {
   	header('Content-Encoding: gzip');
   	echo $file;
   } else {

   and the closing }

   leaving just this:

   <?php
   
   $basepath = dirname(__FILE__);
   
   function get_file($path) {
   
   	if ( function_exists('realpath') )
   		$path = realpath($path);
   
   	if ( ! $path || ! @is_file($path) )
   		return false;
   
   	return @file_get_contents($path);
   }
   
   $expires_offset = 31536000;
   
   header('Content-Type: application/x-javascript; charset=UTF-8');
   header('Vary: Accept-Encoding'); // Handle proxies
   header('Expires: ' . gmdate( "D, d M Y H:i:s", time() + $expires_offset ) . ' GMT');
   header("Cache-Control: public, max-age=$expires_offset");
   
   	echo get_file($basepath . '/wp-tinymce.js');
   exit;

   oh, well if you disable gzip compression in wp-supercache it may go away - check and see.
