Issue

Dear authors, I have a problem with your plugin, every time I try to update wordpress custom registration field it shows me a white screen that says:

A critical error has occurred on your website. Check the site administrator's inbox for instructions.

I deactivated all plugins, changed themes, updated and reinstalled wordpress, but nothing changes. I need help urgently

By deactivating the Woocommerce plugin everything seems to work, but without Woocommerce I don't need this plugin.  :D

How can I solve?
