Got an error during save & verify data

[aijac1314]

I got an error message while saving an app after making some changes in Data Table.

Below as the error message:

Error 403: Something went wrong and your changes couldn't be saved. Please try reloading the page or contacting support.

I tried clear the cache, using a different browser, but still getting the same error.

How to resolve this problem? Your advice is highly appreciated.

thank you.

Try regeneratiing schema in all tables.  The number of columns might be out of sync
