In case one of your switches isn't communicating correctly with your VTP server, you might want to follow these steps.

First, check the VTP info for a working switch. Also take a look at the password, which is being used.

show vtp status

show vtp password

Look especially at the mode, version and the domain.

To configure these parameters use the following commands. Keep in mind you can only configure the version of VTP if it is server. So when you need to change this to version 2, you'll first have to make it server and then change the mode of VTP. Here ae the commands to use:

configure terminal
vtp password <password>
vtp mode server
vtp version 2
vtp mode client
vtp domain <domain>
