• I skipped 4.6 and updated to 4.6.1 and receive this error:

    Warning: Cannot modify header information – headers already sent by (output started at /home/content/xxxx/yy/zzzz/html/wp-admin/includes/template.php:1969) in /home/content/xxxx/yy/zzzz/html/wp-includes/rest-api.php on line 359

    The only other recent changed include trying a different AMP plugin (since disabled and deleted) and disabling Related Posts with Jetpack. I haven’t yet rolled back or disabled Jetpack as other than the error everything *seems* OK.

    The note indicating paying customers get support while Jetpack staff is on leave, but no method is provided to request support.

    Hi there! The first thing to check is whether any other plugins on your site may have a conflict. Please check our Known Issues list here:

    You can also try to deactivate all plugins on your site, and see if that resolves the issue. If it does, then activate them one at a time to determine which is causing the conflict.

    If that doesn’t help, please rule out a theme conflict by temporarily changing your site’s theme to a default theme (such as Twenty Sixteen) and trying again.

    Please let me know how that works for you, and we can go from there!
