Never had problems installing Yoast SEO tools on other sites before.
On a new site I’m building, when I install and activate the plugin, I get the following message
Warning: Cannot modify header information – headers already sent by (output started at /home/cabinetm/public_html/wp-admin/includes/template.php:1642) in /home/cabinetm/public_html/wp-includes/pluggable.php on line 876
I then cannot access the ‘Titles and Meta Descriptions’ tab under the Yoast tools section
