Here’s a screen shot of what i’m seeinghttps://stashbox.org/603958/Picture%204.png

Warning: Cannot modify header information - headers already sent by (output started at /home/clinch/public_html/twilight-wallpaper.com/wp-content/themes/sem-reloaded/inc/entry-admin.php:583) in /home/clinch/public_html/twilight-wallpaper.com/wp-includes/functions.php on line 777

Whats really weird is that I deleted the entry-admin.php file, refreshed and it’s still there.

ANy idea how you would fix these errors?
