Problems with plugin installation on a clean install - WP_CRON SSL Issue

Hi guys,

Just installed on my blog your plugin. After activating it, I started to receive 2 annoying errors.

1.)The following plugins might cause (xml sitemaps) issues with Yoast WordPress SEO: Better WordPress Google XML Sitemaps

- the xml sitemaps for Wordpress SEO is disabled. I would like to know if there is a way to fix or make the error disappear (visual).

2.) Problem communicating with WP_CRON: Peer certificate cannot be authenticated with known CA certificates

- This issue happened right after installing the plugin, no feeds were added. My blog/website has an SSL Encryption in place.

3.) I don't know if there is any connection with the errors above, but the plugin doesn't retrieve any posts at all. Could you please have a look?

Thanks.
