I have just enabled Page Manager on a site that I am developing and wanted to create a new page (admin/structure/pages/add). At the end of the process, when I hit the "finish" button, I get the following error:

( ! ) Fatal error: Call to undefined function page_manager_handler_check_machine_name() in /opt/drupal/home/includes/form.inc on line 3626

/opt/drupal/home is the root of my Drupal installation. The "undefined function" page_manager_handler_check_machine_name is present in sites/all/modules/ctools/page_manager/page_manager.admin.inc .

Any hints about how to fix this issue?

I'm using Drupal 7.34 on Ubuntu 14.04.1 LTS with PHP 5.5.9 and PostgreSQL 9.3.5 on FPM and Nginx 1.4.6.

I can confirm this is an issue. I'll work on a patch.

Reducing this to a "normal" bug because everything appears to still work.

With respect, I disagree about "everything appears to still work". I can't complete my planned page manager workflow because of this. But as a bug, I suppose it is probably normal.

If it helps, what I am trying to do with page manager (and a way to reproduce the error) is demonstrated in this Youtube video:

A Gallery of Nodes with Drupal, Tutorial 2

starting at about 4 minutes and 10 seconds.

@winnall: Oh, sorry, when I tested it and hit upon the error I thought it still work. That said, it's definitely a bug rather than a support request.

This is because the corresponding patch for Panels was never committed: #2410293: Add ability to edit machine names

@DamienMcKenna Thanks for the feedback. Does that mean that installing the patch

https://www.drupal.org/files/issues/panels-edit-machine-names-2410293-4....

will fix the problem?

@winnall: (edit) Maybe? =) I haven't tested it yet.

Since it is a patch for Panels, I suspect it won't help me much: I don't have Panels installed, let alone enabled.

Looked at in this light, I would suggest that it is not a duplicate and suspect that the issue should be reopened.

Although it may clearly have something in common with the Panels issue, it apparently needs to be factored out into a separate solution which will hopefully kill both problems.

I'd like to help, but I have no skills the murky depths of Drupal or PHP, and I've got a website which I need to get into operation by the end of February.

This is definitely a legitimate and rather nasty bug. Here's a first iteration on a patch, it needs a lot of testing but *seems* to work.

@winnall, give this a shot and let me know how it goes. I suspect something similar will also be needed for the Panels and Panelizer versions of this, I'll confirm and get those rolled as well if so.

@mrjmd Thanks for this. I'll have a look at it later today (it's 3:30 in the morning here and I need to get some sleep...).

mrjmd's patch in comment #10 works perfectly.

I discovered the bug while trying to setup a redirect using the page manager HTTP Response code. To test create a new custom page. Set the type as HTTP Response code. Then setup a path and choose 301 redirect as the response, put in a valid URL and click save. Without the patch you get a white screen, with the patch you continue onto the next step.

should this bug stop me from moving from ctools 7.x-1.5 to 1.6?
