This pops up when trying to save a draft.
Warning: Cannot modify header information - headers already sent by (output started at wp-content/plugins/wp-likes/likes.php:216) in wp-includes/classes.php on line 1586
I can still vote on the front end, but sometimes I'm not able to save a draft due to this. What can I do to fix this?
Here is a screenshot, why does this even show up here in the first place?
