Getting the error message when:

https://app.akaunting.com/banking/transactions

Also when attempting to delete a REVENUE.

Please advise.

I just install and messing around I delete the main currency. 
Check if you have any currency and if so, if one of then is set as "main".

Of course, your problem can be completely unrelated to this, just try it.

bet luck!

Thanks Dinosane,

But that didn't work; already have a default currency + made sure all fields have a value.

@Akounting, any input please?

ahhhh!

Due to data being imported from the XLS file, the category didn't match up.

Once the category was saved, the entry DOES get deleted, but the error message still shows up.

Make new company.... click "settings" 

Whoops, looks like something went wrong.

click add new payment again

Whoops, looks like something went wrong.

add anythings again 

Whoops, looks like something went wrong.

If it only happens for additional companies you created and not for the default company that is created at the installation then this currently is a known bug that I and several others already reported:

Hi Everyone,

Please check the new version (1.3.16).

Have a nice day.

Yes 3.16 was released specificaly for this problem.

happy billing

I don't believe I need to update as i'm on the hosted version (on https://app.akaunting.com).

and it's already displaying 1.3.16.

The only thing that needs to be done is adding a message stating that there's a missing fields, so the entry cannot be deleted.
