    WordPress auto-updated to 3.9.1 and all went upside down. Now many plugins don’t work including Google Sitemap plugin and throws canot modify header error

    “Warning: Cannot modify header information – headers already sent by (output started ….themes/hueman-child-master/functions.php:1) in wp-content/plugins/google-sitemap-generator/sitemap-core.php on line 1616”

    login page returns

    Warning: Cannot modify header information – headers already sent by (output started at wp-content/themes/hueman-child-master/functions.php:1) in …../public_html/wp-login.php on line 414

    Warning: Cannot modify header information – headers already sent by (output started at …./wp-content/themes/hueman-child-master/functions.php:1) in …./wp-includes/pluggable.php on line 863

    and it also shows an error message

    “ERROR: Cookies are blocked due to unexpected output. For help, please see this documentation or try the support forums.”

    any help would be highly appreciated

    thanks

  • You have a problem in your child theme. Try switching to the default theme automatically by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

    Thank you for the immediate response Esmi… it actually fixed the header error but what if I want to use the same custom theme?? what can be the reason for this header cannot be modified error??

    Thanks ??

    Since this is a custom child theme, I cannot point to anything specific. Try reviewing Solving “headers already sent” warnings.

    hooo finally I fixed it, the issue was with the format functions.php file was saved.

    The character is a Byte Order Mark(BOM) “a Microsoft invention to tell, in a Unicode file, in which order multi-byte characters are stored.

    To get rid of it, tell your text editor to save the file either as ANSI/ISO-8859 or as Unicode without BOM”.

    To do this in Notepad++ go Format > Convert to UTF-8 without BOM then Format > Encode in UTF-8 without BOM.

    Thanks ??
