Error 500 with yootheme template

[ricoumax]

I used Abook with Joomla 5.4.6 and Yootheme por template. Until version 5.0.14 it's functional, but with Yootheme 5.0.34 I have a 500 error... Thanks

If I create a substitution for  '‎/templates/yootheme/html/com_abook/category/default.php' dans le template 'yootheme'.
I comment line 42 and 47 and it's OK
Idem for Modifier le fichier '‎/templates/yootheme/html/com_abook/book/default.php' dans le template 'yootheme'.

Th line is the problem : <?php // echo JHTML::_('icon.breadcrumb', $this->path);?>
For icon.breadcrumb and icon.search
