“Warning: Cannot modify header information - headers already sent by (output started at”
Any unnecessary new lines, spaces or other characters before an opening
<?php tag or after a closing
?> tag might have caused this as well. If you have a backup of your wp-config.php file on your computer, try to replace the one on your server via FileZilla. Do let us know if you have any queries related to this.
Method 1: Remove your recently installed plugin.
Method 2: Change your php Version.
This may fix your problem.
