Name change to Startup Blog

Hello Milos,
I need to change the name to "STARTUP BLOG", the website is in three languages, in English Canada and French Canada (which read the same) and in Spanish which cannot be seen.
I haven't figured out where I can make the necessary changes for all three languages.
Thank you very much for your help.
All the best.

Hello,

Go to Menus > Top Menu > Home > Page Display. Change the "Page Heading" there.

Regards,
Milos
