Hi I have a strange behaviour with the locale module (version drupal core 7.7.)
Determine the language from the browser's language settings doesn't work - no error message about
I presume it is not a bug - eventually a conflict with other modules - but after disabling various suspicious candidate the phenomen continues - user, session, url and default language is recognized, but not bowser language …

Is their any way to remove/disable/ hide or make email field optional in user registration form in drupal 7 ?

I am using the following to create my gallery

Drupal Colorbox Module
Drupal Views Module
Drupal Ctools Module
Colorbox Plugin

This was working fine until I discovered that the images are stacked vertically instead of in rows. I need a fix for this that is step by step I am a newbie to this and I don't know where to edit my .css file as some of the other forums suggested. So if someone could help me with this it would be greatly appreciated.
Please help! Thanks!
