D7 Add Content is missing content types

Hi,

we are playing around wie Drupal 7 and after installing Panels suddenly all our content types did not show up under Content->Add Content. I found out how to bring them back:

Under Structure click on "edit" at one of the content types missing. In the editor there is the top field "Name", where you can enter a name for this content type and the "machine name" is shown. Click on edit of this machine name. Another edit field pops in where you can edit it. Just add something like "_2" and click on save. Now you should see the content type under Content->Add Content.

Hope that helps,
Phillip

Exact same behavior seen in my D7 install. Discovered that the items for basic page and article had both been marked as disabled (though not by me) in the navigation menu. Re-enabling them under admin/structure/menu/manage/navigation fixed the problem immediately. I also have Views and DateTime installed, but haven't investigated to see if there's any connection.

I had a similar issue, content types not showing up in the 'add content' workflow, even if they were in the admin content type screen. It was a D7 install nearing the end of development, and I can't reproduce the start of the error yet. The navigation menu links had been disabled for a while, with no effect that I noticed. Re-enabling the add content links in the navigation menu resolved the issue. changing the machine name did not resolve the issue.

We could be looking at different bugs, but not being able to reproduce yet means we are in the dark.

I'm having the same problem - also installed Views & Date/Time on D7. I don't want to re-name machine readable name b/c don't want to have issues with menu items. Calendar & Date messed up my D6 site several times - not sure why calendar-type modules are so troublesome. Any other ideas/suggestions?

I noticed that editing the Navigation Menu then caused changes in what content types were showing up when accessing 'Add Content' from other places, such as the Admin menu.

I've made many content types and has been working up until now. Now I don't see added content types in the add content menu. I get a huge error beginning with:

PDOException: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'description' cannot be null: INSERT INTO {menu_router} (path, load_functions, to_arg_functions, access_callback, access_arguments, page_callback, page_arguments, delivery_callback, fit, number_parts, context, tab_parent, tab_root, title, title_callback, title_arguments, theme_callback, theme_arguments, type, description, position, weight, include_file)

Out of the blue

They do not appear at all in the menus

Just made a fresh installation of D7.9 on a testsite, created one content type (called destination) , created some templates using content as output - after adding some content, the Article (Machine name: article) content type is missing - it is present in the "#overlay=admin/structure/types/manage/article", but when adding new content the option to choose article is missing.

Changing the machinename works - and then ofcourse changing the template filenames, rescan, empty cache etc. - this is not an option on production sites :-(

It appears that the content of the 'add content' (article, basic page, book page, etc) is linked to the navigation menu.
We had a customer where 'basic page' was not showing in the 'add content' page.
We reviewed the navigation menu, noticed it was missing from there also and simply added it back .. like so:
1) edit the links of the navigation menu (from the structure menu)
2) click - add link
3) menu title = "Basic Page"
4) Path = "node/add/page"
5) save.

This should fix your problem.

I was having this problem too. Originally i though it was caused by the way I exported my database (without caches), but later I found out that the problem was associated with having disabled the 'add content' links on the navigation menu (which seems strange.) Changing the machine name of the content types caused problems with my views. However, reenabling the 'add content' links caused the missing content types to come back.

Same issue here and I've missing menu entries in the Configuration menu too... still searching for a solution

I had this same issue. After adding another content type (in my case I just enabled the book module), all other content types vanished.
It is connected to the Navigation menu. Previously I had dragged all those content types in the menu to level 1, in order that they were directly accessible. When I now made a reset on every one of those links (in the Navigation menu), and they went back to their original places under "Add content", everything went back to normal, and all content types are back.
I'm now simply going to use DHTML menu module, so that while Navigation menu stays the same, I still can access them directly, without visiting the "Add content" list page first..

I also am seeing the same issue. I recently added a couple of content types but links to neither appeared under the 'Add content' menu in the Administration toolbar and a couple of old ones that I'd deleted were still in the menu. Also, the 'Add Content' for some reason moved to under 'Management' rather than under 'Navigation'. This might have been caused by my monkeying around with the Navigation menu (not at all clear on what its role is meant to be) as I was using it as alternate to the Main Menu in the footer. I was able to clean things up by reconfiguring the Navigation and Managements menu manually but now no new content types I add are automatically added to the 'Add Content' menu at all. Fortunately I'm still in prototyping for this particular site so I can reinstall. None of the other two sites I'm developing seem to have this same problem.

I'm also having issues with this phenomenon after moving all add content links from the default location to a new menu "Create", now some are missing, like Article and Panel.

As another thread mentioned, and I agree, the /node/add and the menus shouldn't be tied together.

I did notice they came back after I'd gone in and edited a link and saved the item and menu forms, but after some time it happened again, unsure if it was because of clearing caches or what.

Fun. Fun.

In my case cache_menu table was missing. after creating table

CREATE TABLE `cache_menu` (
  `cid` varchar(255) NOT NULL DEFAULT '' COMMENT 'Primary Key: Unique cache ID.',
  `data` longblob COMMENT 'A collection of data to cache.',
  `expire` int(11) NOT NULL DEFAULT '0' COMMENT 'A Unix timestamp indicating when the cache entry should expire, or 0 for never.',
  `created` int(11) NOT NULL DEFAULT '0' COMMENT 'A Unix timestamp indicating when the cache entry was created.',
  `serialized` smallint(6) NOT NULL DEFAULT '0' COMMENT 'A flag to indicate whether content is serialized (1) or not (0).',
  PRIMARY KEY (`cid`),
  KEY `expire` (`expire`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='Cache table for the menu system to store router...';

Solution was similar to .htaccess recommendations here, with a twist. In my apache site error log got these errors. First,

[Tue Jan 05 14:04:13 2016] [alert] [client 127.0.0.1] /var/www/html/drupal/sites/default/files/.htaccess: Options not allowed here, referer: http://0.0.0.0/drupal/

commented out the Option lines:

# Turn off all options we don't need.
#Options None
#Options +FollowSymLinks

Then got this error,

[Tue Jan 05 13:51:31 2016] [alert] [client 127.0.0.1] /var/www/html/drupal/sites/default/files/.htaccess: php_flag not allowed here, referer: http://0.0.0.0/drupal/?q=node%2F1%2Fedit&render=overlay

at end of file commented out php stuff,

# If we know how to do it safely, disable the PHP engine entirely.
#IfModule mod_php5.c
# php_flag engine off
#/IfModule

WORKED!!!

NOTE: DID NOT have to comment out the Drupal_Security_... stuff!
