fixed it by this doing regex replacement of dashes with slashes
countdown-timer-widget.php:448
dateAndTime : "<?php echo preg_replace('/-/', '/', $settings['ctw_due_date']); ?>",
I believe that this regex should fix it for dates that are < 999 days.
countdown-timer-widget.php:449
regexpMatchFormat: "([0-9]{1,3}):([0-9]{1,2}):([0-9]{1,2}):([0-9]{1,2})",
I had same issue. I think that downloads.wp.xz.cn has changed directory structure and this plugin hasn’t been updated to reflect latest changes on ww.wp.xz.cn
I had to edit following code in the plugin to update from 1.4.5.8 to 1.4.6
Original Code:
/** Which zip to download in order to upgrade .*/
var $upgrade_url = 'http://downloads.wp.xz.cn/plugin/all-in-one-seo-pack.zip';
Updated Code:
/** Which zip to download in order to upgrade .*/
var $upgrade_url = 'http://ww.wp.xz.cn/extend/plugins/all-in-one-seo-pack/all-in-one-seo-pack.zip';
Then I was able to do one click update.
