It is your theme where the problem comes from.

Thanks.  I thought that I posted the code from that theme file.  Here's the code below, there is an invalid argument on the line with the "foreach" statement.  Anything obvious?

if ( false === $et_updated_plugins_data || ( $has_last_checked && $update_transient->last_checked !== $et_updated_plugins_data->last_checked ) ) {
$et_updated_plugins_data = new stdClass();

if ( ! empty( $update_transient->last_checked ) ) {
$et_updated_plugins_data->last_checked = $update_transient->last_checked;
}

foreach ( $update_transient->response as $response_plugin_settings ) {
$slug = sanitize_text_field( $response_plugin_settings->slug );

$et_updated_plugins_data->changelogs[ $slug ] = esc_url_raw( $response_plugin_settings->url . '?TB_iframe=true&width=1024&height=800' );
}

set_transient( 'et_updated_plugins_data', $et_updated_plugins_data );
}

You should post this to the theme forum. This is the wrong forum!
