Login Problems

Hi everyone,

I attempted to update my wordpress blog to 4.3.1 and when I clicked update it told me wordpress successfully updated however, when I click go to dashboard, it comes up with this message:

“Warning: Cannot modify header information – headers already sent by (output started at /home/content/18/6569118/html/LOSSPREVENTIONV.COM/wp-includes/general-template.php:3057) in /home/content/18/6569118/html/LOSSPREVENTIONV.COM/wp-includes/pluggable.php on line 1207”

Now I continue to see this message whenever I go to wp-admin.

It’s not even coming up with the dialogue for me to place my username and passport.
