Unable to save the changes on my form properly

When I work on any of my forms and I try to save, I get the following error:

Error on Query

MYSQL server has gone away.

Is this a problem at your end?

Apologies for the inconvenience. We had a minor problem with the database and server a while ago, this has been reported and already fixed by our developers. Please do try logging out and log back in to start a new session. But before that, you could also try clearing your form's cache and browser's cache, just to make sure. 

If you are still having problems, please do let us know and we will investigate further. 

Thank you for your understanding.
