As Discussed.
Checking the logs in /opt/datatex/tng/logs/20190822/
you can use this command to view the log live. (user CTRL + C to stop the tail command. )
- Code: Select all
tail -f tng.log
Next open the page with Chrome and then open the developer console. (F12) go to the CONSOLE tab and then try and click on the buttons. Those buttons at the top of TNG are driven with JavaScript and if the error is on the browser side, the console will display the error. If the error is on the software side, the tail command will display the error.
Please show the errors here so that we can check the next steps.
