"Checkout as Guest" and "register/purchase" buttons not showing

[JacoboPS]

Please, could you give me any idea about where could I start looking at*? the web is w w w . 1001especias. com

(Joomla 3.3.6  - VM 3.0.2)

*i.e. in which folder is the file with the code related to those buttons?

[jenkinhill]

The default template file to show those buttons is components/com_virtuemart/views/user/tmpl/edit_address.php  - it is possible that you have a template override for that file that needs updating to work with VM3

What can I say... you are a God to me!  

Yes, the problem was exactly what you said...

I found such file here...
template\name-of-template\html\com_virtuemart\user\edit_address.php

and I just renamed it as _edit_address.php

and now I see the buttons again! Thanks a lot.
