Manage Posts

The MainWP Plugin allows you to manage WordPress posts on your Websites. MainWP Dashboard will allow you to remotely create new posts on your managed sites, edit existing posts, change the status for existing posts, or completely delete them. On the MainWP > Posts > Manage Posts page, you can easily find all existing posts and manage them without the hustle of logging into each child site separately.

Login in to your MainWP Dashboard
Go to the MainWP > Posts > Manage page
In the Search Posts option box set your search preferences
1. Status filters will allow you to narrow down the search to only selected post statuses
2. The keyword field will let you find posts where an entered word is used
3. Date Range will narrow down the search to posts that have been published in the selected date range
Select wanted Child Sits
Click the Show Posts button

Once the Search is complete, a list of found posts will appear at the bottom of the page.

Important Notes

By default, the MainWP Dashboard plugin is set to return (show) a maximum of 50 posts from one Child Site. This is set like this because loading too much data can cause various issues. MainWP Plugin supports only default WordPress Post Types. For managing Custom Post Types, you will need the MainWP Custom Post Types Extension.
