Instructions on configuring Manga+Press are intended for working with the available child-themes for TwentyEleven through -Fifteen (available on Manga+Press' website). Manga+Press supports the TwentySeventeen theme directly out of the box. Other third-party themes may require additional adjustment.
Manga+Press can work out of the box using the available themes for TwentyEleven through TwentyFifteen if there is no need for a Comic Archive page or a Latest Comic page.
4.0 breaking changes!
Manga+Press now supports the default custom post-type archives template for Comic Archives. An end-point for the Latest Comic page has been added as well. Adding new pages is now no longer necessary, though support for pages has been maintained.
Start by creating two new pages in the WordPress Admin, then navigate to Settings > Manga+Press Options. On the first tab, labeled "Basic Options," select the pages you created in both the Latest Comic- and Comic Archive drop-downs. Manga+Press includes templates for both these pages, which are loaded by default. For further fine-tuning, add a custom template to your theme — ideally by creating child-theme of your selected theme. For more information on creating child-themes, see the WordPress Codex article on child-themes.
Note: do not use the Latest Comic or Comic Archive pages as your Home and Posts page (WordPress Admin > Reading Settings) as this will override the queries on those pages and prevent your comics from displaying.
You can change the appearance of the Archive Page. You now have three options: List (default), Calendar, and Gallery. Calendar displays a standard monthly calendar similar to the post calendar provided by WordPress. Gallery will show all comics in a grid layout using that post's thumbnail.
Post sorting order can be changed on the Archive Page. These options are the same basic parameters used by order and orderby in the WP_Query object. The drop-downs don't include the advanced sorting options available for WP_Query (for example: sorting by meta-data, comment-count, etc).
On the "Basic" options tab of the Manga+Press Settings page, the first two options are "Group Comics" and "Use Parent Category." These two options control how navigation between comics is handled. By default, comics navigate between each other regardless of their assigned category.
When "Group Comics" is enabled, then comics are grouped according to their mutually assigned categories. For example, if Comic A and Comic B are a part of Series #1, but Comic C and -D are a part of Series #2, then navigation will exist between Comic A and -B, and Comic C and D — but not between Comics A, B, C, and D.
This option only works when the "Group Comics" option is selected. It works similar to "Group Comics" but the comics are grouped according to their top-most parent category. In this example, Comics A, B, C, and D are assigned to Issue #2.1, which has a parent called Series #2, while the next group: Comics E, F, G, and I are assigned to Issue #3.1, which has a parent called Series #3. Navigation will exist between the comics assigned to Series #2, and to the comics assigned to Series #3 but navigation will not exist between Comic D (Series #2) and Comic E (Series #3).
This setting is intended to control the size of the image displayed. Manga+Press uses the WordPress thumbnail system to create image sizes based on values entered by the user. This is the image-size used on the Latest Comic page. This image can also be loaded in your template using <?php the_post_thumbnail('comic-page'); ?>
The Navigation CSS option allows you to use your own styling with the provided selectors (Custom CSS), or use Manga+Press' default styles (Default CSS).
