Error: You are not allowed to access this application

Shared users with Zoho accounts cannot access my application (forms/views). Only the admin account can access applications. 

Users show up under Account Settings - Manage Users. Accounts are active, and set as users. (Setting to Developer had no affect)

Under Edit This Application - Share Tab - Users have All Forms and Views. Green checks on all forms/views when clicked. 

Under Edit This Application - Views Tab - xxxxx View - Actions/Set Permissions - users have Add/Edit rights. 


I have seen that is a common problem, but I have not been able to solve it by myself. I modified options and I have made various efforts and still not have results would appreciate if someone could help me with this problem.


I have a Standard account and 4 users.


Thanks in advance, I hope someone can help me with this, I'm working on this database for some time, and would please me to make it fully functional.
