message similar to:
configuration option "php_ini" is not set to php.ini location
You should add "extension=uploadprogress.so" to php.ini
solution is something similar to:
pear config-set php_ini /etc/php5/apache2/php.ini
pecl config-set php_ini /etc/php5/apache2/php.ini
Then if you really don‘t feel like touching your php.ini file:
pecl uninstall uploadprogress
pecl install uploadprogress
Oh, and you‘ll still want to restart your webserver since the php.ini changed:
sudo apache2ctl graceful
PECL: configuration option "php_ini" is not set to php.ini location
