Undefined array key "rows" in Search.tpl.php when entering "Manage Groups"
Whenever a user comes to "Manage groups" (/civicrm/group) the PHP warning appears:
Warning: Undefined array key "rows" in include() (line 6 of sites/default/files/civicrm/templates_c/en_US/%%7A/7A2/7A24E297%%Search.tpl.php).
It comes from CRM/Group/Form/Search.tpl:
<div class="crm-accordion-wrapper crm-search_builder-accordion {if $rows and empty($showSearchForm)}collapsed{/if}">
Seems that this code is not correct anymore as stated by Demerit's answer?! https://civicrm.stackexchange.com/questions/42384/undefined-array-key-rows-in-search-tpl-php-when-entering-manage-groups
