Nintex Workflow View reports is broken

Hi,
There could be many reasons for this issue.

1. If you change your masterpage back to the default do you still see this issue?

2. Sometimes this is caused by having too much data to be reported on.
The Workflow History list on the site should not have more than 5000 items in it.
The dbo.workflowProgress table in the Nintex Content database should have no more than around 15 million rows in it.

3. It is possible that SharePoint is blocking the server side script.
This can be enabled in the web.config file.
This MSDN post talks about it:

Thank you Simon for your help.

1. This seems like a needlessly risky solution to something I'm not sure is really a problem.  I don't know if these workflow reports would be useful to me.

2. NintexWorkflowHistory = 2891; WorkflowProgress = 7,629,003

3. Also needlessly risky and I don't know what script to reference.

I was only looking for an easy solution since we are beginning our project to upgrade to SP 2019.

Thank you
