Hi @pragmacafe,

In the future please try to create a new topic for each question you have. This allows us to be more organized and makes it easier for other members to find answers if they have the same questions as you. Doing that would be a great contribution to this forum 🙂

1. By default there is no option to hide this element. However, since this can be resolved with a simple CSS snippet, I will exceptionally provide you with the code to hide this element:

.main-navigation .navbar-nav--buddypress {
	display: none;
}

Please note that we don’t usually provide code snippets (except for fixing bugs before an update) and we are only giving you this as a courtesy.
You can paste this snippet by going in Appearance > Customize > Additional CSS from your admin dashboard.

2. This is a known bug that happens only in Firefox browser. It will be fixed in the next update. Here is another code snippet that should fix the bug while you wait for the next update:

#loginform .login-submit {
   float: none !important;
}

#buddypress .standard-form#signup_form textarea {
   width: 100% !important;
}

#buddypress:not(.youzer) div.dir-search .field_type_textarea label,
#buddypress:not(.youzer) .standard-form .field_type_textarea label {
   margin-bottom: 0 !important;
}

3. The Name field is the only field for which you can’t change the visibility. This is a limitation from BuddyPress and unfortunately we can’t do anything about it. My suggestion would be to rename that field to something like “Username” or “Nickname” and then create your own “Name” field where you can choose your own visibility.

Hope this helps.

Best regards,
