Any idea why all my megamenus lost their product listings? The related views are working fine and I can actually see the products in the HTML source code, but the menus stay blank in every browser I have checked (IE, Firefox and Chrome). It worked fine at least before upgrading from Drupal core 7.35 => 7.38. I have a test site with out-of-the-box (not customized) jollyness theme (and everything else too e.g. modules and database) and it is the same thing there now with empty megamenus.

After hours of debugging I discovered that the problem is caused by this code being added after  <li class="first last leaf block-attach"> in every megamenu:

<a class="menu-attach-block-drop-link external expand-on-click" id="&lt;block&gt;-drop-link-1139" href="# " data-block-id="views|bestsellers-block_1">More</a>

In the view's settings I have "More link" set to "No". Where is this code coming from and how can I get rid of it?

Something has changed in sites\all\modules\menu_attach_block\menu_attach_block.module

I restored this single file from backup and megamenus started working again. I haven't touched the file myself.

Perhaps support needs to make a fix for this issue?

Hello,
