Hi Guys,
On my mangoES box, I've got lots of stuff configured and working, but I've just started having problems editing existing data points...
Nothing else seems to be broken. Dashboards are working, values are updating etc.
If I edit an existing data point and just hit save (without making any changes) - I'm seeing an error in the browser saying "a server error has occurred".
I had a look in the ma.log file and I see the below.
I've tried restarting mango, but this doesn't help.
The last thing I did before I started seeing this was configure a mail server address in the configuration that was timing out on connections, so I then disabled it. Prior to this, everything was working fine. I'm not sure if this is related or not.
Cheers!
