can't add nodes / any content type

You need to describe more about your problem. What are you trying to do, and what happens?

Install devel module, then go to /devel/php and execute the following code (without the open-php and close-php tags)

$item = menu_get_item('node/add');
print_r($item);
$content = system_admin_menu_block($item);
print_r($content);

Save that output as a txt file, then attach to this issue please.

Which user id are you? It looks like there are some content types that are available to be created, if you have access: audiox, degimedia, degimedia-other. If in doubt, use the super-admin (uid 1).

Marking as duplicate of #1234122: 7.7 upgrade unable to add/node.

Did you disable all modules and then re-enable them again?

That fixed my issue.

I failed to mark this duplicate of the other issue but last couple of posts suggest it isn't.

When you say 'none of the defaults do' what do you mean by that? Content types provided by core or contrib modules? From the features module? Please list all modules you have installed on the site.

@captaingeek. The node type table you dumped in the first post here is for Drupal 6, not Drupal 7. Please confirm which Drupal version you're using and whether you upgraded from D6.

To expand on #12, the SQL you included at the top of this issue included:

INSERT INTO `node_type` (`type`, `name`, `module`, `description`, `help`, `has_title`, `title_label`, `has_body`, `body_label`, `min_word_count`, `custom`, `modified`, `locked`, `orig_type`) VALUES

but the correct structure for node_type in D7 is:

mysql> describe node_type;
+-------------+---------------------+------+-----+---------+-------+
| Field       | Type                | Null | Key | Default | Extra |
+-------------+---------------------+------+-----+---------+-------+
| type        | varchar(32)         | NO   | PRI | NULL    |       |
| name        | varchar(255)        | NO   |     |         |       |
| base        | varchar(255)        | NO   |     | NULL    |       |
| module      | varchar(255)        | NO   |     | NULL    |       |
| description | mediumtext          | NO   |     | NULL    |       |
| help        | mediumtext          | NO   |     | NULL    |       |
| has_title   | tinyint(3) unsigned | NO   |     | NULL    |       |
| title_label | varchar(255)        | NO   |     |         |       |
| custom      | tinyint(4)          | NO   |     | 0       |       |
| modified    | tinyint(4)          | NO   |     | 0       |       |
| locked      | tinyint(4)          | NO   |     | 0       |       |
| disabled    | tinyint(4)          | NO   |     | 0       |       |
| orig_type   | varchar(255)        | NO   |     |         |       |
+-------------+---------------------+------+-----+---------+-------+

Which has several differences.

Did you run update.php on the new Drupal 7 install? Node module should have upgraded all of these tables during the upgrade.

I am also experience the same issue after upgrading, only this time in Drupal 7. I've tried everything including the above "enable add content then renable add content in the administration menu" thing. Dumped the cache, ran update.php several times nothing works. I can however create new content types and it will see it, but it can never create existing content types. I could create new content types for everything then copy and paste everything into those new content types, but at that point I might as well recreate the site. After several hours on this I'm half tempted to just recreate the site unless someone has a suggestion... because I'm thinking after pulling my hair out on this for a couple of days, it may be easier/faster just to copy paste and reconfigure everything (and just never update the site *ever* again after this :-/).

I think this is likely a duplicate of #1181030: Node types disabled by _node_types_build() when using node_type_save() with base != 'node_content'. Either way we definitely need more information to be able to debug this, so marking as such.

For what it's worth, I'm experiencing the same problem and found a workaround.

I'm using Drupal 7 (7.23). If I log in as an Administrator and click "content" and then "add content", I get the message "You have not created any content types yet", which is not the case. Also, if I try going directly to this URL:

http://example.com/?q=node/add

I get the same erroneous message "You have not created any content types yet", and again, this is not the case, I do have content types.

HOWEVER, this works for me:

http://example.com/?q=node/add/blog

So in the meantime, until I identify the root cause of the problem, I'm able to add blog posts successfully with this workaround. I just added a blog post and published it, no problem. Also, to add a basic page, this works for me:

http://example.com/?q=node/add/page

I'm assuming you could just replace "page" with whatever other content type you're trying to add.

For what it's worth.
