require_once error

Fatal error: require_once() [function.require]: Failed opening required '/modules/swekey/swekey_integrate.inc.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in ....swekey/swekey.module on line 259

I solved with this:

replaced line 259 with :

$sweekeypath = drupal_get_path('module', 'swekey');
require_once($sweekeypath.'/swekey_integrate.inc.php');

Than the same problem came for line 229. Simply just replaced to the same:

$sweekeypath = drupal_get_path('module', 'swekey');
require_once($sweekeypath.'/swekey_integrate.inc.php');
