Team login issues

We are trying to allow team members to login to our project, but when a member tries to come in through the collaborator login link, it comes up as

Failed to fetch. You must be website admin to execute this action.

How can we resolve this issue?

Hey,

Sorry for the inconvenience, but our backend developer will be offline until Monday, so I won’t be able to check on this issue for you right now, as he is available only for emergencies right now.
In the meantime, one solution you can consider is sharing your account credentials with your team. This way, you both can still work at the same time using the same account.
