      My install was running a little sluggishly recently so I decided on a few improvements. I allocated more heap space to java and I have just upgraded the database to MYSQL from H2. The improvement in all around speed is amazing!!
      Everything seemed to have run smoothly. I can query the database and see data-points created etc.

      However when toggling a data point on/off I am receiving "server error has occurred" warnings. Making changes to the data-point settings is bringing up the same error.

      After going for a quick coffee break, I came back and could toggle on/off, save data-point changes!! It seemed to have resolved itself.

      Any insight into what is happening here would be greatly appreciated.

      Thanks in advance,

      Dominic

        What version of Mango is this? I think something may have gone wrong with the conversion of the units for data points but I'm pretty sure this issue was fixed in the latest version.

          Hi Joel,

          It is version 2.5.0.
          I have figured it out. I had public-dashboards open with the data points being visualised via the API to a local web page. The data points that were being utilised on the page were the points that were giving me an error when I went to amend them. Simply closing the open web page allowed me to edit the data points without error.

          Dominic
