You can either find where the sidebar is being called in your theme, override the buddypress group templates to not have the sidebar or just hide it through plain css.

.buddypress.sd .sd-sidebar {
    display:none
}
.buddypress.sd .entry-content.sidebar-active {
    width: 100%;
}

I assume you’re talking about the group listing when referring to ‘clicking the group’. In that case I believe you’d want to customize the groups/groups-loop.php template by copying it into your own theme and conditionally remove the links if the current user isn’t a member.
Here’s docs on the template hierarchy in Buddypress – https://codex.buddypress.org/themes/theme-compatibility-1-7/template-hierarchy/

That should allow you to control that list of groups and suppress links depending on role.
As to the request access form if for some off chance they make it to that screen, if you want to suppress the form with a blocking message when they’re a member you can use the same template replacement concept to replace groups/single/home.php

Or potentially this plugin by @imath may be more appropriate as you could just make the groups private/hidden;

Please Login to your Dashboard and visit Appearance->Customize-> BuddyPress Nouveau -> Member Front Page.

Uncheck the option “Enable default front page for member profiles.” and publish. The home tab will be removed.

I’m using “Super Socializer” plugin with BuddyPress and experiencing the same issue. However don’t see any options within this plugin. Can anyone recommend another Socializer Plugin that works and allows control over the username?

Your piece of code have saved my day. Thank you so much!

I guess you have solved your problem, after four months. Basically, you have to copy the memmbers/index.php, either from bp-legacy or bp-noveau (depending which you are using), to your theme buddypress/members directory, and modify the order of the options in the select element.

Here’s some info on how to change it
