qlik-multi-kpi becomes an Invalid Visualization

Hello,

We have many extensions installed on our server, including the qlik-multi-kpi extension. We have an issue where, every month or so, any app that uses the qlik-multi-kpi suddenly starts showing "Invalid Visualization. The visulaization was not found on the server. The extension is not available: qlik-multi-kpi".   If I go into the QMC's Extensions list, I CAN see the extension is there. If I go to the QlikShare/StaticContent/Extensions folder.. it's there too!

If I delete/reinstall the extension it appears again. Obviously that's an unacceptable solution if it's got to be done monthly. Has anyone else experienced this problem?  Our server is on Nov 2018, patch 2, soon to be upgraded, which I know is old, but it seems strange that this problem only affects one extension.

Thanks,

Steve

Re: qlik-multi-kpi becomes an Invalid Visualization

Hi,

You get this error not only when the extension is not available on the server at all, but also when the is a problem loading it. The next time this happens, open the browser console and look for errors, like javascript error or HTTP 404 Not Found.

When it happens, does it affect all users (and browsers) at the same time? What browser do you use? Could you try with another one?

HI Eric,

Yes, it happens with all browsers and applications at the same time. We generally use Chrome. Not sure if it's a problem on other browsers, but I'll check. 

The next time it happens I'll open the console window and see if there's anything obvious. 

Thanks,

Steve
