4.0.4 broke layout of site and settings page for the plugin showed
Fatal error: Call to undefined method Fergcorp_Countdown_Timer_Event::getTimestamp() in /homepages/16/d87057129/htdocs/wp-content/plugins/countdown-timer/fergcorp_countdownTimer.php on line 1308
Server is on PHP v5.2.17
Reverting to fergcorp_countdownTimer.php from 3.0.3 works fine on my site.
Thanks for the support and a great plugin Andrew.
