 * Hello,
    I’m not quite sure if the question already has been raised – or is a 
   too easy one, as I’m not fam with php. I installed the plugin in the plugins 
   page and clicked to activate. Then I get the following message: Fatal error: 
   Call-time pass-by-reference has been removed in /usr/www/users/account/wp-content/
   plugins/wp-family-tree/class.tree.php on line 139
 * I tried this recommedation:
 * _This kind of problem is easily solved adding this line to .htaccess in the base
   of your WP installation:_
 * php_value allow_call_time_pass_reference on
 * It did not help.
 * De-installation and re-installation did not help either.
    Can someboday advise?
 * I’m using WP 3.5 with Buddy Press 1.6.2
 * Thanks or helping, Michael

 * OK, I reduced the php-version on my webserver from 5.4 to 5.3
    This helped for
   the moment, although I got errormessages from other plugins.

 * Hi Michael,
 * Did you find another solution to this except from lowering the PHP version on
   the server? I am stack with this and it seems to be the only plugin for what 
   I need to do..
 * Cheers,
    Ele

 * Just go to the error line and delete “&” sign, problem will be solved
