 * Hello,
    This morning as I have been working on my blog all of the sudden my changes
   were not able to modify because I got the following message:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home1/mommyhp2/public_html/wp-content/themes/truly-minimal-wpcom/inc/custom-
   header.php:10) in /home1/mommyhp2/public_html/wp-includes/pluggable.php on line
   1179
 * Now that is what comes up when I try to open my site! Even when I try a private
   window or another browser.
 * I had installed the Icegram plug-in right before this happened. Did that mess
   something up? I have no idea how to fix this.

 * Actually, when I try to delete the plugin I get this message instead “Deletion
   failed: (adsbygoogle = window.adsbygoogle || []).push({ google_ad_client: “ca-
   pub-1966089547995350″, enable_page_level_ads: true }); 0”

 * Now I even get the warning message when I try to login to my admin page! How 
   do I contact someone at WordPress? I need to fix this!

 * It’s not related to WordPress. You can try to seek assistance from someone on
   [http://jobs.wordpress.net/](http://jobs.wordpress.net/) for a small fee

 * I think I was able to fix it after ending up at a FAQ WordPress support page.
   Thanks for the suggestion.
