I tried to log in to my back end and I get the following error message and can’t log in.
Authenticated User Login
Warning: Cannot modify header information – headers already sent by (output started at /home/customer/www/dogcopywriter.com/public_html/wp-includes/l10n.php:335) in /home/customer/www/dogcopywriter.com/public_html/wp-login.php on line 530
then there is another error message reading:
Error: Cookies are blocked due to unexpected output. For help, please see this documentation or try the support forums.
I am not a techie. I have no idea how this happened and what to do. Can anyone help me?
I recently updated to the new version of WP. Just to throw that in.
