For Dashboards with many child sites, the Non-MainWP widget can accumulate thousands of entries, slowing down the Overview page. You can limit the number of entries displayed to improve performance.

​
What You’ll Learn

  • Why large Dashboards need entry limits
  • How to set a custom limit
  • Two methods to apply the setting

​
Prerequisites

  • Choose one method below (using both is unnecessary)

​
When to Use This

Apply this setting if:
  • You manage hundreds of child sites
  • The Overview page loads slowly
  • The Non-MainWP widget has thousands of entries
The default behavior loads all entries, which can cause performance issues on large Dashboards.
1

Install Custom Dashboard

Install the Custom Dashboard extension.
2

Open the extension

Navigate to MainWP > Add-ons > Custom Dashboard.
3

Add the PHP code

Go to the PHP tab and add this code:
add_filter( 'mainwp_widget_site_actions_limit_number', 'mycustom_mainwp_widget_site_actions_limit_number' );
function mycustom_mainwp_widget_site_actions_limit_number( $value ) {
    return 200;
}

4

Adjust the limit

Change 200 to your preferred maximum number of entries.
5

Save changes

Click Save Changes. The widget now displays only the specified number of entries.

​
Method 2: Edit functions.php

Use this method if you prefer not to install an extension.
If you’re not using a child theme, theme updates will overwrite your changes. Consider using a plugin like Code Snippets instead.
1

Open Theme File Editor

Navigate to WP Admin > Tools > Theme File Editor on your Dashboard site.
2

Select functions.php

In the right sidebar, click on Theme Functions (functions.php).
3

Add the code

Add this code at the end of the file:
add_filter( 'mainwp_widget_site_actions_limit_number', 'mycustom_mainwp_widget_site_actions_limit_number' );
function mycustom_mainwp_widget_site_actions_limit_number( $value ) {
    return 200;
}
4

Save the file

Click Update File.
