Hi 1omegazip
By default, the zoom level will inherit the settings of map plugin on your site:
You can generate the code for this map plugin >> Save the plugin, then go to file:
/templates/ja_property/html/com_contact/contact/default.php
Look for this line of code:
<!-- Map -->
<div class="wrap-map">{jaosmap }{/jaosmap}</div>
and replace the default syntax by the code you just generated, for example:
<!-- Map -->
<div class="wrap-map">{jaosmap mode='normal' zoom='6' map_height='640' custom_tile='' }{/jaosmap}</div>
Then clear all cache.
