Block title wrapper only outputs header elements.

I'm unable to reproduce this with the Navigation menu block on a fresh D7.36 site using the Bartik theme and the clean_markup_blocks module, version 2.7.

But, so that I can be 100% sure, could I trouble you to tell me:

• which theme you are using, and it's base theme if applicable (some themes use their own template files which conflict with Clean Markup and prevent the title wrapper from being output properly),
• which element you are selecting for the title wrapper (certain CSS in the theme may hide the title by default),
• which block you are changing the title of (certain blocks don't have titles by default),
• the value of the following settings on the Configure block page:
  • Block title (certain settings may cause it to disappear)
  • Clean markup options -> Additional attributes (malformed attributes can cause invalid HTML)
  • Clean markup options -> Visually-hide block title (this is intended to hide the title field from sighted users, but make it visible to screenreaders).

... this information will help me to determine if whether there's a problem with the Clean Markup module, an incompatibility between the Clean Markup module and the theme you are using, and/or a problem with a specific configuration that's preventing it from working.

Thanks!

I'll check it out. Thanks!

@jremydeaton,

I installed Drupal 7.36, Clean Markup 7.x-2.7, and the Bootstrap theme version 7.x-3.0, and I replaced Bootstrap's theme/block/block.tpl.php with Clean Markup's modules/clean_markup_blocks/block.tpl.php to make it work.

I can confirm that Bootstrap interferes with Clean Markup's ability to override the block title wrapper.

After a bit of investigation, I can confirm this is due to the following line in Bootstrap's theme/block/block.vars.php::bootstrap_process_block():

$variables['title'] = $variables['block']->subject;

... and that removing this line fixes the problem. It's safe to do this because Clean Markup already takes care of this in modules/clean_markup_blocks/clean_markup_blocks.module::clean_markup_blocks_process_block().

Unfortunately, because theme functions in themes always run after theme functions in modules, there's not really any way for me to fix this in the clean_markup module.

A few tips:

• If you haven't already, make a Bootstrap sub-theme, and change bootstrap_process_block() in the sub-theme. This will make it easier to update the Bootstrap theme in the future (e.g.: if the theme maintainers release bug fixes or security fixes).
• To keep your theme accessible, it's a good idea to leave block titles as heading tags, because they allow people who use assistive technology to navigate the page.
