Hello,

I uploaded my newspaper theme website on my ftp, and installed the database. Homepage is working, but when trying to access WP-ADMIN page, this message shows up (i activated DEBUG MODE):

Warning: Cannot modify header information – headers already sent by (output started at /home/licra/www/wp-config.php:1) in /home/licra/www/wp-includes/pluggable.php on line 1219

Help please, website is currently not working 🙁

Thank you

Hi,

Try to deactivate all you plugins, leave only the theme provided plugins active. If you can’t access the the admin plugins screen, disable theme by FTP

Also be sure to check the theme requirements here
– https://forum.tagdiv.com/requirements-for-newspaper/
Theme supports PHP versions up to 7.2, 7.1 or so would be best.

Also check some other similar topics online, like these ones

Thank you,

For all people having the same issue : it was due to wp-config.php being wrongly encoded.

Correct encoding : UTF8 without BOM

Working now !
