How it applies:

These are general guidelines for how Read from file works:

If Read from Map is enabled – and you have a page with header as google page (and this page is a default page), you see all properties pins. That’s how read from file works and applies only for pages with default template and header media set to google maps.

Demo with Read from file Enabled which shows all pins in header google maps with a standard page – https://demo3.wpresidence.net/

If you don’t use Read from file – then the number of pins set in Theme Options apply on the Default Page with header media as google maps.

 
Regardless of whether you have read from file enabled or not,  Maximum Number of Pins to show on the map applies ALWAYS to these pages: 

Requirements:

  • Pins.txt file inside theme folder must have writing permissions (755). Read more on how to set permissions here – http://codex.wordpress.org/Changing_File_Permissions
