Restoring the demo GWBK

Ignition
1

I have downloaded and restored the demo GWBK into ignition 7.7.2 (b2014121709)

I am using MySQL and I have successfully ran the IA demo script that creates the DEMO and MES schemas.

Upon launch of the demo project some items do not work (red overlay), such as historical trending.

Upon trying to run the pages in the designer for demo project I get (for example):

I have verified the DB connection is ok, simulators are running, and the transaction group is running.

I have tried changing the drop down selector to real-time, this also gives errors.

Is there another step involved with restoring the demo project that I have missed?

Based on the errors you posted, it looks like there is not a historical provider specified for those queries. Is there a default database connection set for the project (Designer > Project Properties > Project > General > Default Database)?

It’s working now. I logged a ticket (#8462). Greg suggested I go in and add “[~]” to the start of the tags. When I logged in to make the change, the problem had went away. Thanks.
