The port stay think and I never see the post

Hi Cristian,

seem the issue related with server issue. you server not support simple html dom
simplehtmldom.sourceforge.net/index.htm

cannot read external content. could you please asking your server support? maybe they put some restriction.

Regards

There are not restriction in the server, and is a VPN, therefore support the html dom.

Hi Cristian,

/components/com_community/libraries/akismet.php

JLoader::import('joomla.environment.browser');
