Title: Different Cannot modify header askimet error Last modified: August 18, 2016 --- # Different Cannot modify header askimet error * Resolved [ttancm](https://wordpress.org/support/users/ttancm/) * (@ttancm) * [19 years, 4 months ago](https://wordpress.org/support/topic/different-cannot-modify-header-askimet-error/) * Hi, I’m getting the error: 
Warning: Cannot modify header information – 
   headers already sent by (output started at /home/****/****/ttancm.com/wp-admin/
   menu-header.php:49) in /home/****/****/ttancm.com/wp-includes/pluggable-functions.
   php on line 272
(paths edited out) whenever I use the “delete all” button to delete all the spam Askimet has caught. * I’m not sure if this error pops up anywhere else (it doesn’t show up when posting or using the”De-Spam Marked Comments” button in Askimet), at the present time it only shows up when using the delete all button in Askimet. * I’ve looked over other posts on similar topics and checked line 49 in menu-header. php but I can’t find a problem (it’s possible I am overlooking something though). * Everything works (as far as I can tell), it’s just everytime I delete the spam I get this message and have to click on a menu item to get rid of it. * I have recently installed (and removed) a few plugins, but I have tried with those plugins removed and the problem still remains. * Any suggestions? * Just in case I added my menu-header.php here: [http://wordpress.pastebin.ca/314032](http://wordpress.pastebin.ca/314032) * Any help would be greatly appreciated!

The content is identical (including white space, returns, etc. I compared the two character by character), even though for some reason the file size varies slightly. * Tinkering with things in the problem file has still yielded no results, so I overwrote it with the backup file. Try the delete all button in Akismet again and exact same error. I have actually overwritten the page with a backup, which had no problems what so ever, and I still get the error. * Thread Starter [ttancm](https://wordpress.org/support/users/ttancm/) * (@ttancm) * [19 years, 4 months ago](https://wordpress.org/support/topic/different-cannot-modify-header-askimet-error/#post-502076) * Just installed a newer version of Akismet that was packaged yesterday (Jan. 14, 2007) and that has fixed the problem. * An unannounced error or problem maybe, since this began after updating Akismet and only seemed to affect it?
