On my test server, with error messages displayed, I receive the following:
Notice: Undefined index: wordpresslink in J:\wamp\www\local.example.com\public_html\wordpress\wp-content\plugins\custom-meta-widget\customMeta.php on line 77
The error appears to stem from an invalid index in the
$instance variable within the
widget function. It appears that line 77, which in part reads:
Note that the widget was configured to not display the wordpress.org link.
