Hi @pilsbier1111!
Better Search Replace Support Team here. Thanks for reaching out with your query! We would be happy to assist.
Could you please try setting the Max Page Size to 1000, to see if it helps? If the issue persists, can you try editing your wp-config.php file on your server to replace this line –
define( ‘WP_DEBUG’, false );
With these lines –
define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);
define(‘WP_DEBUG_DISPLAY’, false);
This will cause all runtime errors, warnings, and notices to be written to /wp-content/debug.log, which will hopefully yield some better information about what’s going on.
Can you try the process again and then share the debug.log contents, if created. Feel free to redact any sensitive info. More details about that at https://wordpress.org/support/article/editing-wp-config-php/#wp_debug
Once we have finished troubleshooting you should revert that config change and delete the debug.log file.
As for the checkbox in the test run window, could you kindly share a screenshot or screen recording when the issue happens? Thank you!
