 * A few weeks ago, I started having to login to WordPress through /wp-login.php
   instead of /wp-admin. That’s not a problem, but since this started occurring 
   I can no longer preview my posts or upload certain media (particularly feature
   images).
 * I usually get errors like this that pop up all over the place when I try to preview
   etc:
 * > Warning: Cannot modify header information – headers already sent by (output
   > started at /home2/editor/public_html/wp-content/themes/magazino/functions.php:
   > 3) in /home2/editor/public_html/wp-includes/pluggable.php on line 1173
 * Usually with various numbers at the end though or different links.
 * Does anybody know the fix for this? Using Magazino theme, site is: [glasscity.ca](http://glasscity.ca).
   Thanks.
