I have a similiar problem maybe the same issue, all of the
employees here have the same IP addresss so when an employee likes
something then no one else can like it. Can I just take out the IP
variable from the code?
Yes, we removed the IP address from the array and it is working.
The widget doesn't work however because the posts are custom post
types, how do I get the count on which posts are the most liked?
Can I add a query to the plugin code somewhere so that it will
recognize the custom post type?
Sometimes the plus sign shows on the post but when I click it
the number does not increase. Usually it works just fine but
sometimes it does not increase the number. Is there a limit or a
time limit for liking a post?
