Hi Guys,

a quick explanation of my scenario. I have a custom Drupal theme, with a couple of theme settings and the theme make use of the color module with lots (34) colours. Because of all the colours, I gave them short names and grouped them in a fieldset (all of this done in the "theme-settings.php" file making use of the hook_form_system_theme_settings_alter function. So everythin works 100% and it looks great.

Hi, After installing a new theme and making change in appearance, I have got the following:
Fatal error: Call to undefined function zen_theme() in /home/edutai5/public_html/sites/all/themes/cti_flex/template.php on line 68
Any help please.

I am currently themeing some Drupal and Ubercart template files.

The problem I am having is too many limitations occur in the design when so many fields / elements are contained within the $content or $ variable.

Examples:
Description
Add to cart button
Read more (for the teaser)
Product Image

These will render in their own div tags at times but I would still need more flexibility.

I have searched high and low and see no documentation or process for doing a D6 to D7 Zen theme update??

I have recently migrated a large old D6 site to D7 and thought the data migration would be my biggest problem, until I got to the theme!!

The original developer appears to have themed everything the 'correct' way, using Zens sub-theme process.

There appears to be a main sub-theme and then 3 smaller sub-themes of this.

Can somebody point in the direction of any step by step documentation that could help walk me through the upgrade process?

How I create the front page in drupal 8 using twig?
