Getting a lot of these warning messages.

How do we fix this?

Should we be enabling call time pass by reference?


-------------------------------------
Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file in /home/content/D/a/m/Damselfly/html/modules/xhelp/index.php on line 262

Replace with This will suppress further warning and notice messages introduced by PHP 5.3+. The functions are executed as usual, with or without the messages.
The code itself has to be adapted, when the method in a future PHP version is effective no longer allowed.
