What WordPress theme are you using? Also, when you are in the wp-admin area, go to Settings > Permalinks and make sure the “Permalink structure” is not set to “Plain”.

What might help is that you include a screenshot of the menus and what a page looks like with no content. For example, the following is a screenshot of a page (with content) when the “Activity” menu item is selected:

Additionally, what WordPress theme are you using?

Dear @inspirationacademy,
Unhide the .messages-form .submit (Astra Pro may be hiding it) with:
.messages-form .submit { display: inline-block !important; }
If it’s still missing, copy the BuddyPress messages template into your child theme, add back the <button type="submit" name="send">Send</button>, then clear all caches.

To integrate BuddyPress into your Chipotle menu site and boost user engagement, start by enabling key BuddyPress components like user profiles, activity streams, and groups to let users share reviews, customizations, and tips. Use a lightweight theme like Astra or GeneratePress for better performance, and install caching plugins like WP Super Cache to keep the site fast. You can pair BuddyPress with plugins like rtMedia for photo sharing or Youzify to enhance profiles and community layout. Keep the social features focused on food discussions and menu insights, and avoid adding too many extras to maintain a smooth user experience.

Thanks for the screenshots, they do help. The page shown (General Settings) looks very similar to a page that is provided by the BuddyPress Groups Extras (BPGE) plugin, see the following screenshot:

As indicated in the screenshot, the Home or, in your case, the
Activities tab is fixed in place by the code:

if ( $nav['slug'] === 'home' ) {
	$disabled = 'ui-state-disabled';
}

The above snippet can be found here and just indicates that the Home tab is disabled from being sortable. The following is what the element (li) has as classname (default ui-state-disabled) for a non sortable tab of which the only one is the Home tab.

<li id="position_686f6d65" class="default ui-state-disabled">
     <strong>Home</strong>
</li>

While a sortable tab has default ui-sortable-handle as a classname.

<li id="position_6d656d62657273" class="default ui-sortable-handle" style="">
      <strong>Members <span>1</span></strong>
</li>

The BPGE plugin author claims this change was due to:

Group's "Activity"/"Home" navigation link is hard coded in BuddyPress to always be the first one, so disable its reordering.

However, when I rollback from v3.7.0 to v3.6.10, the Home tab is now sortable and can be moved. So the reason for the change is not entirely true.

Moving along, since the General Settings page from the BPGE plugin is similar to the page from your screenshots, we may be able to infer that there was a fork of some the code (the pages portion) from the BPGE plugin and was included in the BuddyBoss theme which AFAIK is a commercial (paid) theme, meaning I can’t verify the code within this theme due the status of free vs paid. If this is the case, then your resolve will have to come from the BuddyBoss developers. However, if the code that supports manage Page general setting resides elsewhere, e.g., custom code or 3rd party plugin, then the resolve is the responsibility of those who authored the code.

As an aside, as it relates to the BPGE plugin, there is an appearance of wonkiness with the reordering of group tabs which appears to be a factor that caused the change to make the Home tab not sortable, however, I’m not sure if BuddyPress is causing the wonkiness,

Having stated all of the above, it seems to me, the reason that you want the Pages tab to be the first tab is because you want that to be the landing page. Would this be a correct assumption? If so, there may be the possibility of changing the landing page to Pages, regardless of the tab order, which will depend on similar the code is similar enough to the BPGE plugin.

2) … Also there, there is no way to change things here ? Add the thumbnail on the posts list for example, or separate the “comments” and “posts” tabs,…

“Things” can be changed programmatically. Additionally, BuddyPress does not come standard with “Posts” or “Comment” tabs. The only separation for these items is via the dropdown filter selection for “Posts” or “Comments” located in the Sitewide or User Activity streams which is standard for BuddyPress.

3) OK, really confusing.
And if the displyed name and real name arent the same, how can a user know the real @ he has to use to tag someone ?
BTW, i’ve made some tests and even if i use @displayname or @username, it doesnt send a notification to the user,…

Users typically figure out who is who and for @mentions, only the username is used for notifications. For example, a scenario where there are 2 users with the same displayname which happens to be Apple, however, each has a different username because usernames must be unique. Maybe a visual will help you digest this information:

If you are having issues with notifications, that is a different issue and might be related to some external factor such as a plugin or theme that is interfering with the notification process.

As for Main settings, yes, those available via a UI are limited, however, programmatically, there are plenty via constants, filter hooks and action hooks.
