1) How can I change the breadcrumb word “Home” for another one?
–> you have to create page then add it to menu, that page name automatically show in breadcrumb.
2) Why the main menu on the header does not drop-down like in the demo one? Even though that page has multiple child pages.
–> please send your wordpress website login credentials on [email protected] , we will check it.
3) Which contact form did you use so it looks exactly like in the demo? (others will break the size and so).
–> you have to install contact form 7 plugin.
If you can set up website then you will set up, otherwise we will setup your website like as in our demo website.
