how can i change the name of first page?

Not sure what it is you want to change…

Can you tell us exactly what text you want to change.

is about the link name “Home”, in top of my blog, i want to have all my blog translated in romanian and this part is still in english!

Might use something like WinGrep to search your wp-contents folder for the text “Home” to find where that is stored.

the text for “Home” is stored in the header.php

You can edit it to say whatever you want

On the site I administer- https://www.lighthousealliance.org it says “Blog”

correct!
i found it in header.php

thanks again
