Hello there,

Thank you for reaching out to us.

We do not have any such bugs in Amelia so this is most likely issue with the settings or of you created some conflict of roles.

1. In settings general settings you can set the default status of the appointments.

2. Then also this can be changed for each service separately in services edit service settings check of it is set to approved

3. If you set minimum capacity to for example 5 first 4 customers will get pending status until 5th customer books then all 5 of them will get approved status automatically 

4. If you can not change the status of the appointment. Can you please check in WordPress users if you have several roles added to this user? For example admin and employee or employee and customer. etc. Or if this user has the same mail as other user for example admin/manager and employee or employee and customer. etc.

If this is the case then you should know you can not be Admin and manager to admin and employee, etc at the same time since this leads to conflict within the plugin. You need to have only one role per user only admin or only manager or only employee. Every role has different permission and if you combine them Amelia can not function properly.

You need to disconnect other roles from that user and that mail and to create a separate user with separate mail for each role and make sure to purge the cache afterward.

After that Amelia should work properly again. Please do that and let us know how it goes. 

Looking forward to your reply.
