Hi there.
I’m currently using Xibo and sometimes one of my webpages are offline. We use an external business intelligence tool and sometimes it gets offline without notice. We use it as an “embedded item” or a “webpage”. It’d be great if Xibo could detect if there’s 404 or 403 or any other error with the iframe or webpage and then just skip it to next media item. Also you might enable us to search for a specific text string in order to identify if it’s online or not (phpservermonitor has a similar feature)
