How to save changes to /wp-content/plugins/hivepress/includes/blocks/class-toggle.php file after plugin update. I placed in wp-content / themes / listinghive / hivepress / includes / blocks / but it didn’t help. Thanks in advance.
Sorry, unfortunately there’s no way to keep these changes, it’s a core file and it can’t be overridden via a child theme (only template parts can be overridden, you can also override any configs via the API hooks).
Yes, because the Facybox event is still linked to it. If you’re familiar with JS please try to remove all the events linked to this “a” element and the “#user_login_modal” DIV instead, then the modal window will not be triggered at all.
