You have 3 choices.
1. Create new template bits for the profileModern & statusUpdates with new names and use them in the new code changing the new statusUpdates template to choose only ?? statuses in the foreach statement.
2. Change the number of status updates shown for all by editing file adminapplicationsmembersextensionsprofileTabsstatus.php using ftp or file manager.
find
$statuses = $this->registry->getClass('memberStatus')->fetch( $this->memberData, array( 'relatedTo' => $member['member_id'], 'isApproved' => true, 'limit' => 10 ) );
Change the 10 to whatever number you want.
3. in acp system settings > members > user profiles
click add a setting then follow the image
then edit the file adminapplicationsmembersextensionsprofileTabsstatus.php using ftp or file manager.
find
$statuses = $this->registry->getClass('memberStatus')->fetch( $this->memberData, array( 'relatedTo' => $member['member_id'], 'isApproved' => true, 'limit' => 10 ) );
Change the 10 to
$this->settings['maxStatusUpdates']
then the code I made change this
$tab = 'status';
to this
$tab = 'status'; $this->settings['maxStatusUpdates']=1;
You can make the 1 anything you want.
