Warning: Cannot modify header information - headers already sent by (output started at /srv/disk1/1297215/www/higherme.co.uk/Connect_to_MYSQL.php:26) in /srv/disk1/1297215/www/higherme.co.uk/admin_login.php on line 23
This error appears when i try to log in as admin into my websites, also it appears when i try to return using the return button i created. below are the two php scripts which were, the first one is the "admin_login" page which is where the admin aka me will log in and the second is the adminindex which is where the admin will edit the content.
I tried removing spaces which was what some people recommended.
Please help me try to solve this issue. Thanks
