Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
It seems like this file get modified, I already renamed it to
JoomlaFolder/administrator/components/com_easyblog/views/blog/tmpl/default_location.php_back
Then replace back the original file, it should show the location field now.
By the way, this location feature no longer function is because Google already required who using Google Map also need to register an API key from Google account, mean the older version of Easyblog no longer support this location feature.
I would suggest you upgrade to Easyblog 5.
