I upgraded from colorbox module 7.x-1.5 to 7.x-1.6 and from the colorbox plugin 1.3.19 to the most recent 1.4.14.
Installed also Libraries module 7.x-2.1. Drupal core version = 7.22
Modules (Colorbox and Libraries) placed in the right location (sites/all/modules) and colorbox plugin also placed at the right place (sites/all/libraries).
Though colorbox-load (images) is working normally, my existing colorbox-inline content links don't work anymore. When clicking such a link nothing happens but moving to the top of the webpage. The content (text) is not showing anymore in the expected box.
The "colorbox-inline" option is enabled in admin/media/colorbox.
Browsers are IE 10.0.9200.16540 and FireFox 20.0.1.
Went back to colorbox module 7.x-1.5 and previous colorbox plugin and everything works again.
Notice this issue also happens with Colorbox module 7.x-2.4.
Any help much appreciated.
