Comprobamos a través: http://nuestraip/testenvironment.php:

Errors:
• Cannot find PECL_HTTP functions. Make sure that PECL_HTTP Functions enabled.

Solución
# pecl install pecl_http

Añadimos "extension=http.so" a php.ini:


# cd /etc/php5/apache2/conf.d
# echo "extension=http.so" > http.ini
# /etc/init.d/apache2 restart
