Reply To: PHP errors on multiple pages + Elementor not working + Woocommerce errors

Hey,

Checked with WordPress Storefront theme – product pages seem to be fine (without the php error code on top), but checkout still gives error:

Warning: Cannot modify header information – headers already sent by (output started at /data01/virt115716/domeenid/www.vaiketanklad.ee/htdocs/index.php:1) in /data01/virt115716/domeenid/www.vaiketanklad.ee/htdocs/wp-includes/pluggable.php on line 1427

So I guess it’s not because of the theme..

BUT as I am totally confused. Deactivated ALL plugins with WordPress theme and the checkout error code (above) still exists, do you know where should I turn to and what might be the problem, as I can’t seem to find any solution, only to start a totally new website from scratch…

Best regards
