Drupal 7.x

I keep trying to send verification emails but they always give an error.
email could not be sent if problem persists contact admin.
what is going wrong.

After hours of searching about this, i cannot find a solution.

I have follow all the instructions here http://www.brightwebsitedesign.com/how-to-install-views-slideshow-module... and made the tutorial. Everything is ok, except that i only see the first slide and no the others. I have instaled the cycle plugin too.

Is there a way to set a drupal veriable with the contents of a php variable
IE variable_set('var', $phpvar) <-- I realize this is not correct but basicly I want to set the php variable var to the value of $phpvar

Thanks,
Justin

Hola a todos, soy novato y necesito ocultar los metatags a los usuarios de una página web, sin que afecte a sus funciones propias, como puedo hacerlo? Os agradecería vuestra ayuda, un saludo.

Instead of filtering my nodes by the current taxonomy term, I just want those shown first and then the ones that don't, shown afterwards. Is there a way to do this in views?

I am trying to build a prescription glasses site using drupal 7.9 and drupal commerce.

The customer will first have an option to choose a frame. They will then be required to choose the type of lens. Then they can select a lens package and tinting, although the last two will be optional.

Is this possible in drupal and how would achieve this?
