Cannot Modify Header Problem

I recently started having a problem with my site. I started getting this error:

Warning: Cannot modify header information – headers already sent by (output started at /home/somedia/domains/shineon-media.com/public_html/wp-admin/includes/media.php:2080) in /home/somedia/domains/shineon-media.com/public_html/wp-includes/pluggable.php on line 850

Instead of media.php it started out with other files so I went in and deleted extra spaces at the end of the file and then it changed to media.php. Thing is there is no like 2080 in my file.

I logged in to my phpmyadmin and it says this in red: Server running with Suhosin. Please refer to documentation for possible issues.

And i looked at the documentation here: https://www.shineon-media.com/phpmyadmin/Documentation.html#faq1_38 but I can’t figure it out. I can’t login to my admin to post new entries.

Any help would be appreciated. Thanks!
