Updated & broke site

I just updated this plugin and it broke my site, I am getting this error message:

Parse error: syntax error, unexpected ‘[‘ in?/home/p25d95m8/public_html/beta/wp-content/plugins/yith-woocommerce-catalog-mode/plugin-fw/lib/yit-debug.php?on line?237

Please help! I deactivated it via FTP but I need to get the catalog mode working again
