Linkedin error: Access to posting shares denied

After attempting to publish a Drupal post to LinkedIn account we would receive:
LinkedIn.com answered ”< : <

which upon further review of XML from LinkedIn yielded a detailed description:
“access to posting shares denied”

The issue was resolved by:

1. modifying file:
linkedin.inc

by adding line 298 (new)
$xml = str_replace(‘&’, ’&’, $xml);

after line 297
$xml .= ’’;

2. re-generating OAuth Keys for LinedIn module:
OAuth User Token
OAuth User Secret
