Am trying to instal WordPress SEO on a new site and I got this message. Delted, reinstalled. Got same message.
Installed the version from this site, as recommended for when having problems. Still got the message.
Since it is a brand new site, I’d rather not just go with trial and error. Should I just delete it and go with another SEO plugin?
>>The plugin generated 236 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.<<
