Hi,
I have recently upgraded from moodle 3.1 to 3.8.7 (going through 3.5) And everything works fine if using mozilla firefox. But if chrome or edge is used, when any user logs in, it gives error 500.
in error.log I have this message:
FastCGI: comm with server "/var/www/vhost/xxxxx.com/fcgi-bin/php.fcgi" aborted: error parsing headers: duplicate header 'Content-type', referer: https://www.xxxxx.com
PHP versión 7.2
DataBase is MariaDB (barracuda)
Collation: UTF8mb4_unicode_ci
Use Theme Lambda 1.7
How can I solve this problem? Thank you
