Hi @muralimude, don’t worry, this WordPress error is probably caused by your blog’s wp-config.php file, did you edit it recently? If so, for what purpose?

“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.
