MainWP Dashboard warnings: Undefined array key

Bug
1

I’ve created a fresh WordPress installation for testing (translation project) and installed MainWP Dashboard 5.4.0.20. The site is running on PHP 8.4

In the error log there is a constant stream of the following warnings:

PHP Warning:  Undefined array key "title" in /.../wp-content/plugins/mainwp/class/class-mainwp-menu.php on line 498
PHP Warning:  Undefined array key "slug" in /.../wp-content/plugins/mainwp/class/class-mainwp-menu.php on line 500
PHP Warning:  Undefined array key "slug" in /.../wp-content/plugins/mainwp/class/class-mainwp-menu.php on line 501

And sometimes from a different page:

PHP Warning:  Undefined array key "slug" in /.../wp-content/plugins/mainwp/class/class-mainwp-manage-sites-view.php on line 67
PHP Warning:  Undefined array key "slug" in /.../wp-content/plugins/mainwp/class/class-mainwp-manage-sites-view.php on line 71
PHP Warning:  Undefined array key "title" in /.../wp-content/plugins/mainwp/class/class-mainwp-manage-sites-view.php on line 71

Hey @josklever

I couldn’t reproduce these Warning messages.

However, I’ve passed it along to our dev team, and we will have it fixed.

The fix for this was included in version 5.4.0.21 of the MainWP Dashboard plugin, released on Aug 26, 2025.

Thanks again for reporting this to us.
