Plugin Crashes Our Site

Dear Support,

When we install the plugin, it immediately crashes our website when we try to activate it. We literally do not get past the activation stage.

Once the plugin is deleted, the site works again.

This is our staging site where we are testing the plugin:
https://staging.pairfum.com/

Below, we have pasted the status report from WooCommerce for your review.

Please advise because at the moment this plugin is not useable.

With kind regards,

Pairfum London
