well, i updated to php5 and now have everything working there --all extensions, and activation went fine.
as for the htaccess, i created a .htaccess in my main g2 folder and it seems to be checking out, i.e., says "success."
is it normal (and correct or can it be modified) that when i log out of site admin the url left in my browser addy line ends in: /v/?g2_navId=xc9fdf765
??
thanks,
ichiro
