Rennur Opened the app in browser running the 5.7 server & got this error. Appeared when clicked on a Query operation button of 'Run Query' type.
Rennur I disagree; In the samle CRM app, I have added a 'run query' button in a query: 'current alerts dashboard' to view 'all alerts' & the same error pops up. Clean 5.7 install, no bootstrap css. Cheers
