The places you see these warnings. This style is going out of style, in favor of one where you define passing by reference in the function definition. What to do: Change the function calls from: function_whatever( &$var1, &$var2 ); to function_whatever( $var1, $var2 ); and change the finction definitions from: function function_whatever( $var1, $var2 ) { to: function function_whatever( &$var1, &$var2 ) { For now, since these are just warnings you could just turn down error reporting, or enable allow_call_time_pass_reference as shown in the warning, but you should seriously consider fixing the problem by changing the code. Someday soon PHP will no longer allow the old syntax at all.
