After installing media module and creating a gallery with pictures i get the following error's:

I have been looking for a solution to have some site-name letters in various different colors. Though I had a deep look in the various zen css files I could not find any solution. In page.css I found various ways to influence the overall letter color (div#site-name) but not for single letters. I also tried to add some html tags in the Drupal System Site information 'Site name' box but the tags are finally stripped out.

after installing Media module and configuring i create a gallery.

after uploading images and saving i am getting the following error's:

•Notice: Trying to get property of non-object in media_gallery_field_formatter_view() (line 69 of /home/mizarube/domains/mizaru.be/public_html/sites/all/modules/media_gallery/media_gallery.fields.inc).

I created an embed iFrame link to display google on my page, but it can't resolve the website. I am testing the site on localhost and using this as my link:

Not sure how it knows I can even link to the page without a password to get in. I see the browser "cannot display the web page" as when I give a bad link or am not connected to the internet.

I am using D7.4.

I have a vocabulary named 'recipes'. I want a tab/link in the Main Menu to take me to the Recipes category.

I also have a block of QuickTabs setup. Inside this block are individual views for: most recent, most viewed, most comments, most votes- all using the 'recipes' vocabulary as the input.

So when a user clicks on the Recipes Link/Tab on the main menu- they'll be presented with 4 choices- most recent/viewed/commented/voted.

I am looking for the best solution to implement the following using either Commerce or Ubercart (preferably for D7).

Here are the criteria:
1. Customer purchases a single product using PayPal Website Standard.
2. Open checkout completion, user is assigned coupon codes depending on the quantity of purchase. (This quantity will be restricted to 1, 2 or 3).
3. Coupon codes should be emailed to the customer.
4. Store owners should have access to purchases codes.
Also, I need some type of downloadable certificate for the customer to print out.
