Hello, I try to install thle exportGge plugin in my proyect, following the
next instructions:

To use exportGge in your own project you need to:

   - use EPSG syntax for declaring the projection of your mapfile
   - set persistentQueries = false in YOUR_PROJECT/client_conf/query.ini
   - copy demoCW3gge "tables" and "query" coreplugins inside the
   "coreplugins" directory of your project. If they allready exist then you
   need to merge them with the demoCW3gge ones.
   - copy demoCW3gge "exportGge" plugin in your projects "plugins" directory
   - copy demoCW3gge/client_conf/exportGge.ini to YOUR_PROJECT/client_conf/
   and modify the "fileName" value if you want that generated KML files come
   with a different file name
   - copy demoCW3gge "cartoclient.tpl" template file to your project
   "templates" directory or insert :

{if $exportgge_active|default:''}

But when I rendered my project show the messaje
