 * Hey folks, wonder if anyone could give a clue on this…
 * Whenever I try to edit a theme, I get this:
 *     ```
       Warning: fopen([domain details])\wwwroot/wp-content/themes/default/rtl.css): failed to open stream: Permission denied in [domain details])\wwwroot\wp-admin\theme-editor.php on line 44
   
       Warning: fwrite(): supplied argument is not a valid stream resource in [domain details])\wwwroot\wp-admin\theme-editor.php on line 45
   
       Warning: fclose(): supplied argument is not a valid stream resource in [domain details])\wwwroot\wp-admin\theme-editor.php on line 46
   
       Warning: Cannot modify header information - headers already sent by (output started at [domain details])\wwwroot\wp-admin\theme-editor.php:44) in [domain details])\wwwroot\wp-admin\theme-editor.php on line 55
       ```
   
 * In fact, I don’t even have to edit anything – if I just enter the theme editor
   and click ‘update file’ without touching anything, the same thing still comes
   up.
 * Hopefully I can work around it for now by editing the theme files in Notepad 
   and re-uploading them but it’d be nice to have a solution if anyone’s got an 
   idea.
 * Cheers.

 * A brief update, I’ve just discovered that the same error occurs with the plugin
   editor too.
