Remove 'X-Cart. Powerful..' at top of browser ?
 

Can someone please tell me how to change the title of my store homepage ?

I don't see it in home.tpl or head.tpl.

Change your company info in General Settings/Company options.

My company name and URL are already there, the only part of that page this is not complete is the phone numbers because we don't want them on the store. I've updated via the button there.

The top still says X-Cart....

Sorry, my bad. In your version you need to edit a Language variable. Go to Languages, select English, select Text and look for this one:

txt_site_title

Yes, thank you, that did it.
