Today i am sharing you my knowledge on WordPress with jQuery Ajax call.if you are using WordPress core function in ajax call file than you must have to use my tips other wise you will get same problem which i got earlier. Problem was that when i call page in WordPress by ajax its doesn’t showing me any error but call status showing me 404 it means path of file is not correct.but when i type that path in directly than its working fine. So i very tired to solve this error. This problem was happening because i am using WordPress core files in my ajax call files. in ajax_load_map2.php file i am using WordPress core library using include wp-blog-header.php files.
