disable_breadcrumbs error on "/admin/content" page?

This turned out to be a permissions problem, you need the 'administer nodes' permission to do node operations so this access check is now in place. Committed to dev branch.

To work around the error, I changed line 339 to:

  if (array_key_exists('admin', $form)  && array_key_exists('#option', $form['admin']['nodes']) ) {

There's probably a more semantically correct approach that looks at permissions instead.

Works for me. Thanks a lot.

Works for me too, many thanks!

Are you guys saying that you still need this patch with the latest dev version? Or is this just for the 1.3 version? Because a fix was apparently commited to the dev version.

Also, instead of array_key_exists() it is preferrable to use isset(), like this:

if (isset($form['admin']['nodes']['#option'])) {

This isset also makes the first one redundant because for $form['admin']['nodes']['#option'] to exist $form['admin'] must also exist.

Changing it to this worked for me:
if (isset($form['admin']['nodes']['#options'])) {
The singular word "option" didn't.

This is still and issue and none of the solutions posted are working for me. I am using 7.x-1.3

Also not fixed in dev branch.

I see this is still an issue. This seems like a very minor change, I'm surprised it still isn't in a release.

I'm also still struggeling with this problem!

Fix in #8 works for me.
