Hi, I install Rank Math Free plugin, but after I activate the plugin, there's some problems. Warning: php_uname() has been disabled for security reasons in /home/luketrav/public_html/sinchang.com.tw/wp-content/plugins/seo-by-rank-math/vendor/rollbar/rollbar/src/Defaults.php on line 66 Warning: Cannot modify header information - headers already sent by (output started at /home/luketrav/public_html/sinchang.com.tw/wp-content/plugins/seo-by-rank-math/vendor/rollbar/rollbar/src/Defaults.php:66) in /home/luketrav/public_html/sinchang.com.tw/wp-admin/includes/misc.php on line 1126 How to solve this two problems?
