WSOD: Call to undefined function linkedin_get_profile_fields() in linkedin/linkedin_profile/linkedin_profile.module on line 96

I have this as well. I posted a couple comments on http://drupal.org/node/795936 but this issue seems to be narrower in focus. My twist to it is, I only get the failure when I go to system node paths (i.e. node/x). If I go to the alias path, no problem found.

The module does not find linkedin.inc, Just put this in the first line of linkedin_profile.module

/*
* Require .inc
*/
module_load_include('inc', 'linkedin', 'linkedin');

Ok, cool. I knew it was something simple.

Should this go alone or inside this function after the other module_load_include line?

function linkedin_profile_init() {
  global $theme_path;
  $li_css = $theme_path . '/linkedin_profile.css';
  if (file_exists($li_css)) {
    drupal_add_css($li_css);
  }
  else {
    drupal_add_css(drupal_get_path('module', 'linkedin_profile') . '/linkedin_profile.css');
  }
  module_load_include('pages.inc', 'linkedin_profile');
}

It has to be outside the init function, I got more intermittent errors with OAuth, and ended in copying almost everything from the linkedin.module init function into a new function linked_module_init.

Lousy coder here, so my patch might confuse most people, however, here is what I put

 module_load_include('inc', 'linkedin', 'linkedin');
 module_load_include('pages.inc', 'linkedin', 'linkedin');
  if (!@include_once(variable_get('linkedin_liboauth_path', ''))) {
    if (file_exists(drupal_get_path('module', 'oauth') . '/oauth.lib.php')) { // Cope with OAuth module 6.x
-2
      variable_set('linkedin_liboauth_path', drupal_get_path('module', 'oauth') . '/oauth.lib.php');
    }
    elseif (file_exists(drupal_get_path('module', 'oauth_common') . '/lib/OAuth.php')) { // Cope with OAuth
 module 6.x-3
      variable_set('linkedin_liboauth_path', drupal_get_path('module', 'oauth_common') . '/lib/OAuth.php');
    }
}

Should be fixed in dev, by ensuring the file is loaded before calling the function.
