I am experiencing the issues too, anyone has found why is happening with this plugin?

For the moment, you can edit youtube-channel-gallery.php to avoid the problem temporarily:

$transientId = 'ytc-' .md5( $ytchag_feed . $ytchag_user . $ytchag_maxitems );

$videos_result = $this->get_rss_data ( $ytchag_cache, $transientId, $ytchag_rss_url, $ytchag_cache_time );

if(is_wp_error($videos_result)) return; // Adding this line 

$rss = simplexml_load_string( $videos_result['body'] );

It was a Transposh option. Probably conflicting with the cache, I disabled the MO/PO compatibility and it works nice now.

And what is the point on backing up a non visited blog?
