Wordpress Theme PHP7 Fix

We are seeing a couple of PHP errors on our Wordpress site after updating to PHP7:

Warning: Use of undefined constant HTTP_USER_AGENT - assumed 'HTTP_USER_AGENT' (this will throw an Error in a future version of PHP) in /**/html/zwp-jrp2s on line 1

Warning: Cannot modify header information - headers already sent by (output started at /**/html/zwp-jrp2s:1) in /**/wp-includes/pluggable.php on line 1251

Warning: Cannot modify header information - headers already sent by (output started at /**/zwp-jrp2s:1) in /**l/wp-includes/pluggable.php on line 1254

We would like somebody to fix the PHP7 issues for us, so we can continue to use our theme. It’s a theme from Themeforest but the author is no longer supporting it so we’re looking to hire somebody to fix it.

The theme and latest database will be provided via Github to the chosen candidate.
