Display Issue for Knowledgebase after update

After the update to Pro 4.0.5, I am now having issues with displaying Knowledgebase Archives on this link: (https://firstoptionbank.com.au/article-categories/access/

It worked under Pro 3.x.x releases.

Hi @digitalinnovations,

It seems that there is a critical error in the given URL. There are a few possible reasons for the issue and can help after having the exact errors.
Please add the below-given code into your wp-config.php for debug setup, and the error logged into the file name debug.log inside the wp-content folder.
You can let us know if you find any error that is related to our theme or theme bundled plugins. We can do further investigation based on that.

// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );

// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );

// Disable display of errors and warnings 
define( 'WP_DEBUG_DISPLAY', false );
//SET PHP INI DISPLAY ERROR FALSE
@ini_set( 'display_errors', 0 );

Please find the video that will help you to edit wp-config.php and add the above code: https://www.youtube.com/watch?v=3SDPTafEM8o

Hope it helps.
Thanks
