Hello,
How can I remove the register section in the template ( I can't find it in the module)?
You need to just go to the Vertex admin area under the General tab and remove any text for register there and then it won't show on the frontend.
Also, I want to change the address in the "Where" Section, where I had coordinates for the address, I don't full the address format as its found on the website
This address that is on top of the map is a custom HTML module published to the "custom_5" module position.
Change the copyrights Section?
This can be edited in the /vertex/footer.php file.
Home page title ?
This can be changed under the Joomla menu manager area. Just go to your main menu and select the "home" menu item and in there you'll see a parameter for "page title" I believe it is.
