Call to undefined function category_node_get_categories()

I'm unable to reproduce this bug. Please provide additional information, such as:

- Do you have caching enabled? If so, of what type(s)?
- Did you install alpha1 fresh, or upgrade to it? Please note that there is currently no upgrade script.
- What is your environment? PHP version? MySQL / Apache version? OS?

Have the same problem, not sure what it could be, had to disable the module.

My chrystal ball says you people had uploaded module with it's containing folder, something like module/category-6.x-2.0/category/category.module . If this i the case, moving it up to module/category/*.* should help

Bumping this down out of critical until someone can provide some clear steps for how to reproduce this bug. I've tested category with regular and aggressive caching enabled (caching has been known to cause problems like this in the past, due to hook_init sometimes not being fired), and still haven't encountered it. Thanks.

I had the same error.

I had installed the category module in my sites/all/ directory. Deleted and reinstalled into the /modules directory and it seems to work fine.

Nope. When I went to log in, the admin side quits with a similar error.

So it seems the category module wants to be on /sites/all/ when in admin mode and /module/ when in normal unlogged browse mode.

I am taking the module out until I find a solution.

Hi Mike,

Did u found a solution for this problem finally?

I was also getting this error. It seemed that category.inc was not being loaded. I did some comparison and noted that category.inc was being loaded in the hook_init function, while some other modules loaded their *.inc files in the hook_theme function. Also after doing some research on hook_init, I noted that it sometimes doesn't load things right (http://drupal.org/node/342131). So I moved the line
require_once dirname(drupal_get_filename('module', 'category')) .'/category.inc';
inside the hook_theme function (function category_theme() {).

That did the trick! No more Call to undefined function category_node_get_categories errors.

I hope this helps others.

I'm going to close this in favor of #338750: Fatal errors - category.inc sometimes not loaded? - both the issues have a similar discussion, but I simply came across the other one first, and closed a few other duplicates in favor of that one already. The category queue is sometimes difficult to digest...
