We can do some browser troubleshooting to get rid of the error you're getting when trying to record a BAS payment.
First thing we'll need to do is to access your account on a private browser. A private browser does not store any activities, which is why it's a good idea to use it for any unexpected behavior in the program.
Here are keyboard shortcuts you can use depending on the browser you're using:
If you're able to access your record the BAS payment without an error, then go back to your default browser and clear your browser’s cache. It is a good idea to clear cache, to remove the temporary internet files and to help the application function properly.
You can also do the browser health checkup as an added step.
Feel free to share an update after doing the steps above. Thank you.
We're glad to hear it all worked out for you, trish28.
