Olá, Ariel! Tudo certo? 
Pelo que a gente pode perceber no erro, existe algum tipo de conflito com o plugin woocommerce instalado no seu WordPress.
Eu acabei renomeando as pastas relacionadas a ele e o site já está abrindo novamente.
As pastas renomeadas estão dentro de /public/wp-content/plugins/ e ficaram assim:
woocommerce/ —> woocommerce_cliente/
woocommerce-admin —> woocommerce-admin_cliente/
Dessa forma, o plugin não está respondendo e, por conta disso, não gera erros no site.
Como forma de correção, você pode analisar especificamente o que está acontecendo com o plugin para ajustar ou reinstalar para começar uma configuração dele do zero.
Caso ainda tenha alguma dúvida ou dificuldade, estou à disposição!
Até mais
