I was just updating my plugins and wordpress and found the following issue: Warning: Cannot modify header information– headers already sent by (output started at /hermes/waloraweb076/b170/moo.cypressridgecottages/ highstreetmotorinn.com.au/wp-admin/includes/template.php:1642) in /hermes/waloraweb076/ b170/moo.cypressridgecottages/highstreetmotorinn.com.au/wp-includes/pluggable. php on line 876 * Thread Starter [sirquentin5](https://wordpress.org/support/users/sirquentin5/) * (@sirquentin5) * [13 years, 3 months ago](https://wordpress.org/support/topic/header-error-wp-includespluggablephp-on-line-876/#post-3470904) * Fixed it. I replaced the functions.php file of my theme with the original file that I downloaded again. * [Angela](https://wordpress.org/support/users/g33kg0dd3ss/) * (@g33kg0dd3ss) * [13 years, 3 months ago](https://wordpress.org/support/topic/header-error-wp-includespluggablephp-on-line-876/#post-3470989) * Hi, Sirquentin! Do you know which portion of your functions.php file was causing the error? I’m getting the same error, and I’m about to start poking around in my functions.php file to see what’s causing the problem. * Edited to add: Whoops, my error was the same, but with a totally separate cause( attachment extender plugin). I disabled the plugin, since it’s pretty unnecessary now anyway. Please disregard! 🙂 * [Lucas](https://wordpress.org/support/users/luquerias/) * (@luquerias) * [13 years, 3 months ago](https://wordpress.org/support/topic/header-error-wp-includespluggablephp-on-line-876/#post-3471020) * Hi, i found a simple solution that worked for me. Simply take the wp-config.php file, open it in a text editor and click save as. It will try to save as UTF- 8 file, save it as ANSI. As i said this worked for me… * [positiveproductivity](https://wordpress.org/support/users/positiveproductivity/) * (@positiveproductivity) * [13 years, 2 months ago](https://wordpress.org/support/topic/header-error-wp-includespluggablephp-on-line-876/#post-3471091) * this is also happening to me and I just started my website.

It will try to save as UTF-8 file, save it as ANSI.

I also tried to use the text editor but when I click save changes it just gives me the message that I made no changes. By the way I’m doing this in my hostgator cpanel. * [Lucas](https://wordpress.org/support/users/luquerias/) * (@luquerias) * [13 years, 2 months ago](https://wordpress.org/support/topic/header-error-wp-includespluggablephp-on-line-876/#post-3471096) * First of all, download the file to your desktop. Then open it with a text editor, save as ANSI and upload it overwritig the file that is on the server. What operating system are you using? * [Lucas](https://wordpress.org/support/users/luquerias/) * (@luquerias) * [13 years, 2 months ago](https://wordpress.org/support/topic/header-error-wp-includespluggablephp-on-line-876/#post-3471097) * I have read that the the ANSI equivalent might be Western (Windows Latin 1) or Western (DOS Latin 1) * [Levi](https://wordpress.org/support/users/wheatstate/) * (@wheatstate) * [13 years, 2 months ago](https://wordpress.org/support/topic/header-error-wp-includespluggablephp-on-line-876/#post-3471100) * Changing the UTF to ANSI doesn’t fix this problem. There’s a plugin problem somewhere, but there’s not enough information to discern what plugin is giving you the heartache here. * [oklamax](https://wordpress.org/support/users/oklamax/) * (@oklamax) * [13 years, 1 month ago](https://wordpress.org/support/topic/header-error-wp-includespluggablephp-on-line-876/#post-3471109) * **Fixed!!!**I had this Line 876 Warning also, You should Go to WordPress Index. php file and make sure nothing is above the Opening php tag, For some reason I had on top of . * I had to put a closing ?> at the end of my functions.php and made sure there weren’t any spaces or line breaks. * [Ryan Burnette](https://wordpress.org/support/users/ryanburnette/) * (@ryanburnette) * [13 years ago](https://wordpress.org/support/topic/header-error-wp-includespluggablephp-on-line-876/#post-3471121) * Same here as well.
