You can see it in action here https://katesgasis.com/archives/.
The installation was a breeze. Just upload the file kgarchives.php to your /wp-content/plugins folder and create a page with posts <–KGSortForm–> and <–KGSortArch–>.
It lets you sort your archive by months and then group it by category before showing you the daily posts within that category.
Example:
April 2005
Category 1
30: post in category 1
29: post in category 2
.
.
Category 2
30: post in category 2
29: post in category 2
.
.
March 2005
Category 1
30: post in category 1
.
.
Category 2
30: post in category2
.
.
If you want to show only all the post in a specified month just select the month in the archive form. To display all, select All Months.
Geez, it’s that easy.
