MotorOctane on "[Plugin: XML Sitemap & Google News feeds] Issue with post dates"

Hello, I just installed the latest version of the Sitemap. I was using it previously and I have now got back to this sitemap. For some reason, it cannot see any posts in 2015.

http://motoroctane.com/sitemap.xml

and http://motoroctane.com/sitemap-posttype-post.2015.xml is showing as empty, whereas it has posts that were written in 2015.

Are there very many posts in 2015? It might be a case of running into the server/hosting PHP memory limit. Try setting the option "Split by: Month" on Settings > Reading under the XML Sitemap settings.

Other thing I notice is that you are using WP Super Cache in Legacy mode but Late Init is not set. Is there any specific reason for using legacy mode? Is there any possibility to switch to the recommended PHP caching mode?

Thank you Ravan H for the response. I got it changed to month and even started PHP caching mode. However, now when I click on 2015 or any other year. It just opens the website than any sitemap.
