This looks like you have a PHP error in your site, which is causing the redirects from S&F to fail.
Try to track down your errors using WP_DEBUG – https://codex.wordpress.org/WP_DEBUG
Once you resolve your issue, the redirects should work again.
Thanks
Thanks for support, I can look is a problem with ColorMag wordpress theme, I am testing anothers themes and works fine, I think is a problem after last theme update… 🙁
Same problem here with
WARNING: wp-admin/admin-header.php:9 – Cannot modify header information – headers already sent by (output started at /websites/123reg/LinuxPackage22/se/ah/ol/seaholly.fr/public_html/wp-includes/functions.php:1)
require_once(‘wp-admin/admin-header.php’), header
Any help would be appreciated
Hey, this means you have a PHP/WP error in your site.
Its not a S&F problem, it just means the PHP error is preventing the page from redirecting – which is what S&F does to direct you to a correct results page.
You will need to debug your site, find the cause of the error and remove it.
I already provided a link above to get you started.
Thanks
