Log In Problems

Try logging in to the …/wp-admin/ and get the following text on the page:

Warning: Cannot modify header information – headers already sent by (output started at /home4/akritzer/public_html/akmcusa.com/wp-content/plugins/wordpress-easy-slides/wp_easy_slides.php:1) in /home4/akritzer/public_html/akmcusa.com/wp-content/themes/smallbiz/functions.php on line 160

Tried to log in using /wp-admin.php and also cleared my cache

How can I access my admin page and how can I fix this?

Any help would be appreciated. Thanks!
