Erro ao Cnfigurar

Oi, Gabriel!
Tudo bom?

Primeiramente, parabéns pelo plugin!

Eu instalei no woocommerce, mas depois que ativo e aperto em configurar, recebo a seguitne mensagem de erro:

PHP Warning: in_array() [function.in-array]: Wrong datatype for second argument in E:\home\cozinhafit\Web\wp-content\plugins\woocommerce\classes\abstracts\abstract-wc-settings-api.php on line 590PHP Warning: in_array() [function.in-array]: Wrong datatype for second argument in E:\home\cozinhafit\Web\wp-content\plugins\woocommerce\classes\abstracts\abstract-wc-settings-api.php on line 590PHP Warning: in_array() [function.in-array]: Wrong datatype for second argument in E:\home\cozinhafit\Web\wp-content\plugins\woocommerce\classes\abstracts\abstract-wc-settings-api.php on line 590PHP Warning: in_array() [function.in-array]: Wrong datatype for second argument in E:\home\cozinhafit\Web\wp-content\plugins\woocommerce\classes\abstracts\abstract-wc-settings-api.php on line 590PHP Warning: in_array() [function.in-array]: Wrong datatype for second argument in E:\home\cozinhafit\Web\wp-content\plugins\woocommerce\classes\abstracts\abstract-wc-settings-api.php on line 590PHP Warning: in_array() [function.in-array]: Wrong datatype for second argument in E:\home\cozinhafit\Web\wp-content\plugins\woocommerce\classes\abstracts\abstract-wc-settings-api.php on line 590
