Hi, I have the same kind of error when I tried to upgrade PHP 7.1 to 7.3
I get this error:
Backend fatal error: PHP Fatal error: Uncaught ArgumentCountError: Too few arguments to function WP_Job_Manager_Post_Types::maybe_add_default_meta_data(), 1 passed in /home/WEBSITE/domains/WEBSITE.nl/public_html/wp-content/plugins/wp-job-manager/includes/3rd-party/wp-all-import.php on line 17 and exactly 2 expected in /home/WEBSITE/domains/WEBSITE.nl/public_html/wp-content/plugins/wp-job-manager/includes/class-wp-job-manager-post-types.php:1011\nStack trace:\n#0 /home/WEBSITE/domains/WEBSITE.nl/public_html/wp-content/plugins/wp-job-manager/includes/3rd-party/wp-all-import.php(17): WP_Job_Manager_Post_Types->maybe_add_default_meta_data(2913)\n#1 /home/WEBSITE/domains/WEBSITE.nl/public_html/wp-includes/class-wp-hook.php(288): wpjm_pmxi_saved_post(2913)\n#2 /home/WEBSITE/domains/WEBSITE.nl/public_html/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(”, Array)\n#3 /home/WEBSITE/domains/WEBSITE.nl/public_html/wp-includes/plugin.php(465): WP_Hook->do_action(Array)\n#4 /home/WEBSITE/d in /home/WEBSITE/domains/WEBSITE.nl/public_html/wp-content/plugins/wp-job-manager/includes/class-wp-job-manager-post-types.php on line 1011\n
