My archive page has the following:
<h2 class="archive">Archive: [+wp_month+] [+wp_day+] [+wp_year+]</h2>
[[Ditto? &parents=`2` &id=`wp` &extenders=`dateFilter` &display=`6` &filter=`id,16,2` &dateSource=`createdon` &dateFormat=`%A, %B %d %Y at %l:%M %p` &tpl=`blog_post_summary_tpl` &depth=`3` &paginate=`1` &paginateAlwaysShowLinks=`1` &hideFolders=`1` &seeThruUnpub='1' &sortDir=`DESC` &filter=`id,16,2|id,21,2`]]
And the doc pointing at the archive page:
[!Reflect? &id=`wp` &config=`wordpress` &targetID=`16` &getDocuments=`1` &dittoSnippetParameters=`parents:2|depth:3|hideFolders:1|seeThruUnpub:1` &monthSortDir=`DESC` &tplContainer=`blog_archive_container_tpl`!]
I’d say your Ditto call is missing &id=`wp` ...
