Hi,
1st enquiry:
open this PHP file:
/plugins/system/vm2_cart/vm2_cart.php
and to the top of this PHP file (right after
<?php, include this line:
The warning messages will be gone.
Those are just warning to inform the webmaster, but everything works as expected. It is safe to hide those messages. That line above will hide them.
About your 2nd and 3rd enquiries, Those are generated by 2-Joomla and 3-Virtuemart Component so they have nothing to do with our Template. We don't provide free support if the problem/issues are not caused by our Template. (in fact those are not error/problem at all, they are a custom modification) But i will try to guide you though, which is all i can do.
2nd enquiry:
Look at this topic: I just found it on google.com
stackoverflow.com/questions/12808024/how-to-edit-edit-profile-and-view-profile-page-joomla-2-5
