8. Do you have any plugins other than BuddyPress installed and activated? If so, which ones? Yes (list is long so I’ll detail if needed)
This is likely to be the issue. Sometimes a rogue plugin will cause problems. Your best bet is to deactivate each plugin, one at a time, and check to see if the issue gets fixed. As soon as the reg page begins to work, bang, you have your culprit.
I’ve not used the plugin myself so am not familiar with how exactly users are confirmed or unconfirmed. Try opening a topic on the plugin’s support forum asking this same question.
You’d need to use a dummy email for each user as the email field is required. It doesn’t need to be a real address, just something you can use as a placeholder until they log in and change it. For example:
If it’s a BuddyPress page then I guess the bp_core_fetch_avatar() function should display the local avatar if no Grav exists. Are you saying this doesn’t happen?
So wp_mail_from works for all email notifications aside from private message email notifications? If that’s the case then this is likely a bug. You could open a ticket for this on Trac.
Unfortunately there isn’t a page which shows a list of working and broken plugins. However, you can use the WordPress review system and support forums to check what people are currently saying about a particular plugin. If it works, any bugs or issues should all be posted there.
This might be due to a plugin you have activated or perhaps even the theme you’re using. Try disabling all plugins and reverting to Twenty Fifteen. Does the search return offline users now?
As Hugo points out, index-register.php should be an entire document (with a header and footer). The template you copied (register.php) is what’s known as a “partial” and is usually included within a document.
BuddyPress can do all of these things right out of the box. Regarding point 5, you will need to disable both the private messaging and activity components. That can be done from the admin area in a few clicks.
