So I came to know by searching that I need to set my Access-Control-Allow-Origin: or Origin tags. But where?? Suggestions were to use these in header.
I can't see find anything that explained this. Can anyone please tell me where to put this tags and how!!
In your PHP file * I guess you have ajax request, etc.*
<?php
header('Access-Control-Allow-Origin : *');
...
in the header sent by the server (so, nothing to do with javascript or jqueeery)
and the correct answer is thanks to @Jaromanda X .
<?php header('Access-Control-Allow-Origin : *'); ?>
in top line
