Love this plugin but it’s not working now … error:
Warning: Invalid argument supplied for foreach() in /var/www/vhosts/myXXXurl.com/httpdocs/wp-content/plugins/breadcrumb-navxt/breadcrumb_navxt_admin.php on line 591

Well it is a warning, not an error. This problem has been reported several times already, including several times on this forum, no need to add a new post. This is already fixed in the SVN trunk version. BTW, the issue you are experiencing is only present in multi-site setups.
