Thank you very much for purchasing the theme. I apologize for the delay but I have been traveling this week.
For item 1 – MENU URL, that has to be edited in Menu – Edit Menu Item and type your URL. WordPress imports demo as it is on demo, and you have to edit after that.
For item 2 – For Latest Sales and Rentals , you need to check the Recent Items IDs and make sure they match your domain. In import wordpress assigns unique IDs and those need to be updated manually.
In this video I explain how to check IDs – https://www.youtube.com/watch?v=paLIfipA3b0#t=122 Hope it helps.
If you need more help, please let me know.
