Error message on WP dashboard

Please tell me how to deal with this message on my site dashboard.

For the plugin to perform properly make sure those settings on your server in the following states.
cUrl extension is enabled
Safe mode is off(only for below php5.4)
“Open_basedir” option is disabled
Otherwise enable “allow_url_fopen” setting

Thank you.
