It seems like there are two custom code snippets in toolset custom code with same function name. But I don't know how to deactivate them as when I activate the plugin.. the site crashes and I can even access wp-admin.
Taking a look at this error, it seems you have activated the function that has the same name of another. What you can do is to log into your site using FTP and delete this file /wp-content/toolset-customizations/add_parent_taxonomy.php
