Yes, orderby=”date” is the publication date.
orderby=”modified” is modified date (last time you edited it).
Are you sure the post date is changing? In the shortcode you can add include_date=”true” to show the post’s date. That might help troubleshooting.
This matter was NOT RESOLVED but had to move on since there did not appear to be a resolution. I RECENTLY DISCOVERED the problem and it relates to a plug-in incompatibility with POST TYPES ORDER. (https://ww.wp.xz.cn/plugins/post-types-order/)
Since one manually rearranges post order via a drag and drop interface I can see as how it might not play well with others. When i deactivate POST TYPES ORDER your plug-in DISPLAY POST SHORTCODE sorting by date works just fine. Unfortunately I have a need to rearrange post order quite often.
Is there some conditional code that i might be able to add to functions.php that can circumvent or mitigate this incompatibility issue?
THIS IS JUST ONE EXAMPLE…
http://washingtongrovemd.org/meeting-minutes/
2017 TC MINUTES …July 2017 shows at the top (these minutes were added after the fact but date of post publication was edited to fit into the chronology)
[display-posts category=”town-council-meeting-minutes” tag=”2017” posts_per_page=”13” include_date=”false” order=”DSC” orderby=”date” include_excerpt=”false”]
When I deactivate the POST TYPES ORDER plug-in it all sorts out correctly (between June & August)
I recommend you use a different ordering plugin, like Simple Page Ordering, that does not affect WordPress queries throughout the site.
When you want to order by the manual order you’ve specified, you use [display-posts orderby="menu_order" order="ASC"]
The other ordering methods (like date) remain unaffected.
Thanks Bill…will check it out
