This is caused by the following piece of code in app/design/frontend/smartwave/mango/layout/local.xml (such a template in such a location does not really exist in any of the themes):
<action method="setTemplate"><template>catalog/category/page_header.phtml</template></action> The only one existing template is located in app/design/frontend/smartwave/mango/template/page/html/page_header.phtml
Has someone any ideas on how to correct this issue, without causing any impact on the webshop?
The entire xml code looks like this:
<catalog_category_default> <reference name="root"> <action method="setTemplate" ifconfig="mango_settings/category/page_layout" condition="one_column"><template>page/1column.phtml</template></action> <action method="setTemplate" ifconfig="mango_settings/category/page_layout" condition="two_column_left"><template>page/2columns-left.phtml</template></action> <action method="setTemplate" ifconfig="mango_settings/category/page_layout" condition="two_column_right"><template>page/2columns-right.phtml</template></action> <action method="setTemplate" ifconfig="mango_settings/category/page_layout" condition="three_column"><template>page/3columns.phtml</template></action> </reference> <reference name="page.header"> <action method="setTemplate"><template>catalog/category/page_header.phtml</template></action> </reference> <reference name="left"> <remove name="tags_popular"/> <remove name="catalog.leftnav"/> <block type="core/template" name="catalog.category" before="-" template="catalog/category/main_categories.phtml"/> </reference> </catalog_category_default> <catalog_category_layered> <reference name="root"> <action method="setTemplate" ifconfig="mango_settings/category/page_layout" condition="one_column"><template>page/1column.phtml</template></action> <action method="setTemplate" ifconfig="mango_settings/category/page_layout" condition="two_column_left"><template>page/2columns-left.phtml</template></action> <action method="setTemplate" ifconfig="mango_settings/category/page_layout" condition="two_column_right"><template>page/2columns-right.phtml</template></action> <action method="setTemplate" ifconfig="mango_settings/category/page_layout" condition="three_column"><template>page/3columns.phtml</template></action> </reference> <reference name="page.header"> <action method="setTemplate"><template>catalog/category/page_header.phtml</template></action> </reference> <reference name="left"> <remove name="tags_popular"/> <block type="catalog/navigation" name="catalog.category" before="-" template="catalog/category/category_nav.phtml"/> <reference name="catalog.leftnav"> <action method="unsetChild"><child>category_filter</child></action> </reference> </reference> </catalog_category_layered>
