I am getting a Error! Please check your selected file and try it again error when I try to import an app from another development server. Both are community editions.

A new version appears on top of the existing version but it has no PROCESS however FORM, LIST and USERVIEW are there.

I tried exporting several times but as the result is still the same. 

What is the cause of this issue and how to solve it?

    Hi there,

    Do you get any error message in your server log? It's good if you can check on this area to help you to troubleshoot.

    Thanks.

      Hi Garrett,

      Try to verify if you have created form that uses "sc_registration_student" as a table name. Let us know on your findings.

      Cheers
