Hello Senthur !

1) UNA Video app doesn't require the RMS installation. As you were told above (thank you, MyZoid Vapour !) your current Cron looks at least "not usual". You can check to see when your Cron Job last ran by going into Studio > Dashboard > click the arrow next to Server Tools and click Server Audit. Scroll down until you see  Last cron jobs execution. If the time is far from the current moment then your Cron command couldn't be completed.

2) Looks like you have the redirect code - did you add something similar recently? If not - then please PM me with the UNA studio access of your site.
