@healthsectionhooghly, it seems like you have crossed the submission threshold for your account. I could see a lot of projects with a lot of submissions there. If you accumulate, it’s just over the threshold the system provides.
So you will either need to delete some of your projects (along with the submissions) or subscribe to a paid plan if you wish to have all the projects (and the submissions) in your account.
If you wish to subscribe, please reach us through info@kobotoolbox.org. We could help you facilitate subscribing to a paid plan.
