  • Try to login with the following link.
    https://www.vehicletrackingdirect.com/wp-login.php

    If you can successfully login, then change the theme to some default WordPress theme.

    If those error messages are still visible, then try to deactivate all plugins & activate one by one to find the culprit.

    I deactivated debug and now it all loads OK, not sure that’s actually solved the issue though!
