The same problem! Need solution, please.

Same question as I asked before

What version of joomla?

Do you have any extensions installed?

version of Joomla 3.5.1. No extensions, I even reinstalled joomla 3.6 in other directory with new database - the same problem. Even changed version to php 5.6, but the warning is still there. Don't know what the reason is actually. What can it be? I use localhost (root, whithou password)

May be it wasn't at first and then appeared, I can't exactly say it.

Warning: Parameter 1 to ContentHelper::countItems() expected to be a reference, value given in D:\OpenServer\domains\joomla-test.local\administrator\components\com_categories\models\categories.php on line 403

The Problem is in this commit:

d2577b7#diff-edb981daf19f46ce73d3828ab0df8454R400

@bembelimen didn't notice that

call_user_func(array($cName, 'countItems'), $items, $section);

can't give parameter per reference to the called function and in PHP 7.0 this raises a warning.

I use Joomla 3.6, I changed it to $cName::countItems($items, $section); and it works again without warning.

btw. in this commit in line 395 there is $prefix = ucfirst(str_replace('com_', '', $component)); which is redundant to line 388 $eName = str_replace('com_', '', $component); so replaceing this with $prefix = ucfirst($eName); would be a good idea.

Thanks a lot! The problem is solved.

Had the same problem
Joomla 3.6 with several extensions and PHP 7.0.9
