Pimcore: areablock.php: ucwords() filled with 2 params

[solverat]

since commit https://github.com/pimcore/pimcore/commit/e07b9ec4e5bc8ca64f5cb94c41550ad89a24c583, the method ucwords is called with wrong amount of parameters:

Warning: ucwords() expects exactly 1 parameter, 2 given.

Thanks.
The 2nd parameter of ucwords() is supported since 5.5.16, so I guess you're using a version lower than that. I've patched this, since we still have support for 5.5 in version 4.
