Hi Tai,
Have you added around 500 URLs? If so, this is a fairly common bug caused by the way the interface is designed and PHP’s default limit to the number of inputs it will process in one request. A workaround is available here https://wordpress.org/support/topic/cannot-enter-more-then-499-entries?replies=13#post-5462272

I tried the work around you referenced but I am having issues when I do what Ben suggests. After looking through other support tickets it looks like others are having errors as well. Any suggestions on what we are doing wrong? I can create a new support ticket if you like.
I’m having the same issue.
Is there any update on the fix? For us who don’t know code and doesn’t really understand the workaround a really good plugin is now useless.
