Ajax error viewing alerts

[Nubicola]

Describe the bug
When I click on "Alerts" for a specific host, I get a popup message: DataTables warning: table id=table_alerts - Ajax error. For more information about this error, please see http://datatables.net/tn/7

from the web_interface.sh I see the following error:

Hi Nubicola. Thanks for the report. We are working to solve this.
We used to have this error before, and it was fixed, but it seems it is back.
The issue is that sometimes we modify the backend DB structure and some parts of the web are not updated.
Thanks!
