single-tournament.php

Hello,
i have a little problem. i tried to edit single-tournament.php file.
i tried to remove
Line 20: ‘tournament_server’ => esc_html__(‘Server: 192.168.0.1’, ‘arcane’),
and 48: if (isset($tpostmeta[‘tournament_server’][0])) {
$arcane_t_data[‘server’] = $tpostmeta[‘tournament_server’][0];
because i want to host tournaments on consoles and there are no servers..
It didn’t work as planned, and after reuploading original file it’s not working like before. When i click on create tournament, a blank page opens up.
