Sitemap.xml Additional Pages

I started to use the Additional Pages feature on the sitemap tab. I noticed having not manually entered a Last Modified date that the options stored in the db ended up empty.

In the aioseop_sitemap.xml the date conversion around line 2272 when used with an empty date string returns 1970-01-01. We had entered a lot of URLs before I released so I implemented a temporary solution adding a basic check

$mod = (empty($mod) ? date(“Y-m-d”) : $mod);

just above this line

$mod = date( ‘Y-m-d\TH:i:s\Z’, mysql2date( ‘U’, $mod ) );

If useful could be added to the plugin for future updates?

All the best
