I've got error:
Warning: Cannot modify header information - headers already sent by (output started at /wp-content/plugins/easywpseo/onpageseo-admin-license.php:3) in /wp-includes/pluggable.php on line 881
"The plugin generated 2 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin." Was this supposed to happen? Thanks :)
Edit: Nvm re-installed it and no warnings were shown!
