Drupal 7.x

I see a lot of D7 videos where when they go to Views, their page looks completely different then what I see. I'm currently using Seven on D7.

Running Drupal 7.1 I've got this error in my Recent log entries report with the type "cron":

FieldException: Cannot change an existing field's type. in field_update_field() (line 231 of /var/www/ydama/modules/field/field.crud.inc).

Can't find any details or related issues in core.

pls help ! how can i make photos, videos .... show on my page again ?
thanks,
Love & peace

I have a couple of functions that I use in rules, and snippets throughout the site. Currently I have just copied the contents of the function to each snippet, I need to know the best way to implement this as a function that I can simply call from any snippet box, rather than duplicating code.

Create a module and then call it somehow, or is there a custom include I can add with some functions...?

Thanks in advance.

Hi all,
I am new user of drupal CMS, and I was wondering how to change the view of comments to show all my website comments in Blocks??

I am trying to build a community website.
The problem I am facing is that i need a complex profile type. Every user is basically a company and it can have many team members. These are part of the profile itself. But the functionality I want here is that in the profile, the user can add multiple team members and these inturn have their fields like name, designation etc.
I can implement them as content type, but that is not what i really required. I want them to come as a separate link, and not when user clicks on add content.

Any help shall be deeply appreciated.
