upgrade from 1.5.6 to 1.5.8a, php 8.1

This is new issue for the display logs plugin itself? I removed the 3.01 so this is 3.02 - don't see that it was installed before. Now getting this constantly. I don't see a change in the plugin itself since I last upgraded a site to 1.5.8. What am I missing?

HTML Code:
#0 [internal function]: zen_debug_error_handler()
#1 /zenmin/includes/init_includes/init_templates.php(49): define()
#2 /includes/autoload_func.php(40): require_once('/home/xxx/p...')
