Whenever i try to save options i get the following error. Warning: Cannot modify header information - headers already sent by (output started at E:\HostingSpaces\acca\accapastpapers.com.pk\wwwroot\wp-config.php:1) in E:\HostingSpaces\acca\accapastpapers.com.pk\wwwroot\wp-includes\pluggable.php on line 934
I would recommend you disable all plugins and enabling them one by one. Also make sure you don't have any empty space in a wp-config.php file.
