Types is a WordPress plugin that lets you easily create custom taxonomies and organize your custom content types in your website.
When you ask for help or report issues, make sure to tell us what you have created so far and what you want to achieve.
The issue here is that the customer is unable to add a new taxonomy using our Types plugin.
Solution:
Sometimes issues like this can be caused by a plugin conflict. I would recommend temporarily disabling all your non-toolset plugins and try creating the taxonomy again
