Android errors in events

Hope someone can help…

Just wondered why one of my Android devices shows a black cross in the status?
It seems to be working ok with the correct campaign.
Also the event log for the device is absolutely full with the folllowing
69446 06-12-2017 08:25 Cannot delete file: /var/www/cms/library/ticker_6c58e7f0bfac796436b06a1f1f3fc500

Etc etc…

We have another identical android device that show all ticks but the event log is still full with the above.

Thanks

The device may be Android, but those messages are from the CMS not from Android.

To see why the cross is there, you need to use the “Manage” button on that display’s entry in the Displays page.

Once on Manage, you’ll see a list of widgets and files, each with their status. Any that are not complete will show up with a cross there.
