Can't use string ("member_directory_sort_POSTCOUNT") as a symbol ref while "strict refs" in use at CGIPath/ubb_profile.cgi line 1584.
Code
 			@sorted[ $sp .. $ep ] = sort $method @sorted[ $sp .. $ep ];

Can't use string ("member_directory_sort_PDN") as a symbol ref while "strict refs" in use at CGIPath/ubb_profile.cgi line 1725.
Code
 			if($order[$orderdex] ne chr(255)) {
				@sorted[ $sp .. $ep ] = sort $method @sorted[ $sp .. $ep ];
Any idea how I'm to fix these errors? <img src="https://www.ubbcentral.com/boards/images/graemlins/confused.gif" alt="" />
