Update Notifications Error

Hi,

I am using Update Notifications plugin and 2-3 days ago when I entered my admin panel it showed me an error and now it shows me error every day.

Have to say that it shows only main page of panel and only once a day. For example, I have just opened my dashboard (firstly today) and it showed me this error on top, but as I refresh or change page it is disappeared..

Here is the error:

Warning: Invalid argument supplied for foreach() in /home/eblogge/domains/eblog.ge/public_html/wp-content/plugins/wpmudev-updates/update-notifications.php on line 349

Warning: Cannot modify header information - headers already sent by (output started at /home/eblogge/domains/eblog.ge/public_html/wp-content/plugins/wpmudev-updates/update-notifications.php:349) in /home/eblogge/domains/eblog.ge/public_html/wp-includes/functions.php on line 861
