Thanks for your prompt response.
I had changed from 0 to 200 but have kept “Blocking or custom” in panel and it is working fine right now. But I am having following problem ;
(1) I am using filter for region ( Example North America and United States under it). Now there are certain post attach to both North America & United States. When I select only United States in the filter, I do not get the post which are attach to both North America & United States. Let me know what I am missing.
(2) Also I want to put up year as one of the filter for the posts. Let me know if it is possible.
Again thanks for your prompt response.
