Ola a todos

- HTTP request status Fails
Your system or network configuration does not allow Drupal to access web pages, resulting in reduced functionality. This could be due to your webserver configuration or PHP settings, and should be resolved in order to download information about available updates, fetch aggregator feeds, sign in via OpenID, or use other network-dependent services.

- GD Image Filtering Low Quality / Poor Performance
The installed version of PHP GD does not support image filtering(desaturate, blur, negate, etc). It was probably compiled using the official GD libraries from http://www.libgd.org instead of the GD library bundled with PHP. You should recompile PHP --with-gd using the bundled GD library. See http://www.php.net/manual/en/image.setup.php. An implementation of imagefilter in PHP will be used in the interim.

- GD Image Rotation Low Quality / Poor Performance
The installed version of PHP GD does not support image rotations. It was probably compiled using the official GD libraries from http://www.libgd.org instead of the GD library bundled with PHP. You should recompile PHP --with-gd using the bundled GD library. See: http://www.php.net/manual/en/image.setup.php. An implementation of imagerotate in PHP will used in the interim

eu ja reinstalei o lamp para resolver o problema do GD mas nada ainda , e o problema do HTTP request tenho quase certeza que é problema de DNS mas num to conseguindo resolver , se alguem souber de algo me ajuda por favor.

Abraços a todos.
