cannot access the admin

Hi,

My site went off line this morning, I had access to it through the safe mode but it now will not let me access. The problem is a plugin, An error of type E_ERROR was caused in line 19 of the file /home/emeraldisleseawe/public_html/wp-content/plugins/woocommerce/includes/class-wc-api.php. Error message: Uncaught Error: Class ‘WC_Legacy_API’ not found in /home/emeraldisleseawe/public_html/wp-content/plugins/woocommerce/includes/class-wc-api.php:19

Could someone help with this, please note I have limited technical skills.

Kind regards

Trevor
