If I install the extension, i get:

Fatal error: Call to a member function getQuery() on a non-object in /home/wdodamo/public_html/includes/menu.php on line 36

Fatal error: Call to a member function connected() on a non-object in /home/wdodamo/public_html/libraries/joomla/session/storage/database.php on line 85

If I uninstall, it is all good.

Lastest Joomla ...

Help please, thanks.
