Hi Pablo, thanks a lot for getting back to me and trying to fix the error! I appreciate it. I have updated the plugin. Unfortunately, when changing to the wp_mail function in the plugin, I still get the error:
1. I get the email asking me to verify the email. When I click the link (https://xxx/my-account/?alg_wc_ev_verify_email=…), I get a critical error.
2. In the dashboard, I get the warning that the email is not verified. When I click the link, I also get the critical error.
