Fatal Error: Call to undefined function understrap_get_select_control_class()

Hi Understrap Team,

I am experiencing a fatal error when accessing the “Posts” page in the WordPress admin panel. Here are the details:

Error Message:
Fatal error: Uncaught Error: Call to undefined function understrap_get_select_control_class() in /wp-content/themes/understrap/inc/widgets.php:44
Stack trace:
#0 /wp-includes/class-wp-hook.php(324): understrap_add_block_widget_categories_class(‘<select name=’…’, Array)
#1 /wp-includes/plugin.php(205): WP_Hook->apply_filters(‘<select name=’…’, Array)
…

Steps to Reproduce:

1. Log in to the WordPress admin panel.
2. Go to “Posts”.
3. The page crashes with the fatal error.

Environment:

• WordPress version: 6.7.2
• Understrap version: 1.2.4
• PHP version: 7.4.33 (planning to upgrade to 8.1 soon)
• No recent updates to Understrap or new plugins installed

Temporary Fix:
I commented out the following line in /inc/widgets.php (line 44):
// $class = understrap_get_select_control_class();
After this, the “Posts” page loads fine, but I assume this is not the correct solution.

Question:
Was understrap_get_select_control_class() removed in a recent update, or is it missing in my installation?
Any guidance on how to properly resolve this would be greatly appreciated.

Thanks for your help!
