Title: Undefined pp_get_groups() error Last modified: May 26, 2022 --- # Undefined pp_get_groups() error * Resolved [Xavier Serrano](https://wordpress.org/support/users/xavierserranoa/) * (@xavierserranoa) * [4 years ago](https://wordpress.org/support/topic/undefined-pp_get_groups-error/) * getting this error An error of type E_ERROR was caused in line 121 of the file/ code/wp-content/themes/crate/inc/filters.php. Error message: Uncaught Error: Call to undefined function CShop\Crate\pp_get_groups() in /code/wp-content/themes/ crate/inc/filters.php:121 * setting \pp_get_groups() does not work either. do we need to do something to make sure the api file press-permit-core/library/api-legacy.php is loaded correctly when trying to use the function from a hook in the theme files?
