Hi,

We are testing 8.1.11 on our servers. And after completing the upgrade the MQTT Transmission server page does not load anymore. It returns a ‘Internal error’

org.apache.wicket.WicketRuntimeException: Error attaching this container for rendering: [WebMarkupContainer [Component id = table]]

Is reinstalling Ignition the only solution?

Thanks

Check the gateway logs (or the `wrapper.log` file if you can’t access them) for the full details of the stacktrace.

If it happened immediately after installing a module, then the obvious thing to try would be uninstalling that module.

We managed to solve it just now.

Ju8st uninstalling/reinstalling module did not work.

What we did was:

1. Uninstalled module
2. Deleted the tables related to module in idb (internal db)
3. Reinstalled module which recreated the tables

Page started working

Thanks,
