Gallery navigation buttons not displaying

I have also this issue, where I'm totally missing the Colorbox gallery function. I've been searching an answer why this happens - no luck so far. I can see from HTML source that all is correct (rel='gallery-all') and everything. Because HTML is correct and js plugin also loaded, I can initiate the Colorbox gallery behavior manually this way:
First open [Firebug] JavaScript console and then give this command:

(function($) {
    $("a[rel=gallery-all]").colorbox({rel:'gallery-all'});
})(jQuery);

Now the gallery is working.

So what went wrong and where with the module?

I have done everything according the instructions found on Colorbox front page, although I haven't used drush. Colorbox version is 7.x-1.3 and for plugin 1.3.19.

Live example: http://pekkapoika.fi/drupal/node/10

I believe this is a bug in the latest version of the Colorbox plugin. I can replicate it by upgrading to v1.3.19.2 of the plugin.

I have made an issue over at the Colorbox Github project about this, https://github.com/jackmoore/colorbox/issues/194.

Until it is resolved I recommend using an older version go the plugin.

I have attached v1.3.19 below.

Brilliant, problem solved with the attached version.

Thanks, frjo.

Jack More has committed a fix, see https://github.com/jackmoore/colorbox/issues/194.

If you download the Colorbox plugin now you get v.1.3.19.3. If you have time, please test and report back here.

frjo, the new plugin v.1.3.19.3 solved the problem. Thanks!!!!

Re-downloading official Colorbox Worked for me too, thanks.

I am using Colorbox 1.4.33 and have no arrows, only close button.

I have the same situation, even with the newest modules and plugin files, but only where I use "Insert module" to insert link to Colorbox image into text.
If this applies in your situation, just replace rel="gallery-all" with rel="gallery-node-nid" where nid is the id of your node.

I have just tried current colorbox with jquery.colorobx.js 1.5.9(2014/4/25) in fresh Drupal 7.30 installation, Firefox 31, Ubuntu 14.04.1.

Only Collorobx, Library API and jQuery Update modules were installed. Using Batrik theme.

Tried with multiple-value image field, and inline body images with "colorbox" class end rel="galler1" for grouping.

Everything is grouped OK, and Previous, Next, Close buttons are visible using default and 1.5-1.10 jQuery versions (provided by jQuery Update).

So, seems there are no problems, at least in "clean" Drupal installation.

Fixed the Issue 10/04/25
I had the issue with Drupal 11 and colorbox not displaying Next or Previous arrows.

I have fixed the issue for my website when all other answers Did Not Fix the Issue.

In order to get the next and previous arrows to display, I used the colorbox Default display and the colorbox configuration has the slideshow enabled in: https://coverjunkies.com/admin/config/media/colorbox Options - Custom - Slideshow settings = ON.

Then in the Drupal - Structure-Content Type you have created for your colorbox gallery go to Manage Fields - Manage Display, click the small gear on the right - On the next page choose the - Gallery (image grouping) option, save the change and clear the Drupal cache.

Hope this helps you because it was the only thing that worked for my site.

Cheers
