Question

Look at the image above and try the url at -> http://domainsoutlook.com/s/site/stackoverflow.com.html and go to server information tab.

The absurd point I notices is that if I load http://domainsoutlook.com/s/site/stackoverflow.com.html#server_information

then the map loads fine

Answer 1

You need to call checkResize() API function after you changing the tab.

First of all move declaration of map variable upper, for example:

var map;
$(document).ready(function() {
//... your code

And then after tab is clicked call map.checkResize() function.
