We are unable to fetch this data problem!!!!!!

I'm trying to access my database "suppliers list form view" but it prompts the following error:

We are unable to fetch this data, sorry!
Please note that your data is SAFE.Report this problem to support@zohocreator.com

I've also tried to deleted a field and create another one on the same form but I just can't do it. Could you please help me to fix this problem asap.

Thanks.
