Function _panels_page_menu_item is not implemented

I got:

warning: Invalid argument supplied for foreach() in /Applications/MAMP/htdocs/MyDrupalSite/sites/all/modules/panels/includes/plugins.inc on line 1225.
warning: Invalid argument supplied for foreach() in /Applications/MAMP/htdocs/MyDrupalSite/sites/all/modules/panels/includes/plugins.inc on line 1123.

As well.

same here.
PHP 5.1.2

* warning: Invalid argument supplied for foreach() in /var/www/web1/web/sites/all/modules/panels/includes/plugins.inc on line 1225.
* warning: Invalid argument supplied for foreach() in /var/www/web1/web/sites/all/modules/panels/includes/plugins.inc on line 1123.

Do we need a check for !empty($contexts) on lines 1225 and 1123 (panels_context_get_keywords & panels_context_get_form. Works for me, but makes me wonder if I'm not building the panel correctly - or maybe my check always returns false :)

I'm also having this issue.

I'm having a similar situation...
I create a new 2 pane panel, save through the various steps, and when I try the URL it fails, with 'page not found'
If I then go back to edit the panel and click save once more, the URL works, but I get the same '* warning: Invalid argument supplied for foreach()' errors as above.

Drupal 6.2 (I know...), PHP 4.4.7, Panels 6.x-2.0-alpha1, Clean URLs on

I also got these errors on panel page

* warning: Invalid argument supplied for foreach() in C:\AppServ\www\sites\all\modules\panels\includes\plugins.inc on line 1225.
* warning: Invalid argument supplied for foreach() in C:\AppServ\www\sites\all\modules\panels\includes\plugins.inc on line 1123.

sorry ;P

UPDATE: found solution on this node http://drupal.org/node/304199

I'm not seeing these errors. I believe that they may be fixed in -dev already. CAn anyone confirm?

Still getting the error. Don't know if I am the only one. Fresh install 6.6 and panels dev version snapshot 2008-Nov-17

* warning: Invalid argument supplied for foreach() in /sites/all/modules/panels/includes/display-layout.inc on line 210.

After I got the errors. I tried this patch http://drupal.org/files/issues/plugins.inc__4.patch but failed
HUNK #1 failed at 1120
HUNK #2 failed at 1224

I didn't try this one http://drupal.org/node/307591 because of Merlin's comment.

Same thing here. A bit frustrating because it's holding up my 6.x update.

In my panel I went ahead and enabled "menus as tabs" option. This caused the white screen of death with this error:

Fatal error: Call to undefined function _panels_page_menu_item() in /ebs/sdk/webapps/drupal/drupal-6.8/sites/all/modules/panels/panels_page/panels_page.menu.inc on line 372

Just to be sure I grepped the whole codebase for " _panels_page_menu_item" and found that it is called, but never declared.

Yup, and the comment immediately above the call to that non-existent function notes that it doesn't exist.

In -dev, that entire section of the configuration is now just disabled (read: gone); we have enough problems with the menu system as it is without trying to handle that headache.

Sorry, but unless someone decides to dig in on that code and write a patch, it just ain't gonna happen in 6.x-2.x. I just don't have the cognitive latitude to think about yet one more dimension of menu insanity right now. You'll probably have to wait for what we pull together in Panels3.

Panels 2 is no longer available and is unsupported. Marking all Panels 2 issues won't fix.
