Hi @WYamout

From which version of Magento did you upgrade?

In Magento 1.9.2.4 there is no method named isSubCategoryMod in Mage_Catalog_Block_Category_View  class.

Were you using any custom module with lower version? Try to search this isSubCategoryMod method in community and local code pool of original site.

THanks that helped found the class it was a custom class in view.phtml

Now though have another problem

the page is opening but products not showing saying...

Fatal error: Undefined class constant 'DM_SUBCATEGORY' in/home/admin/web/domain.com/public_html/app/code/core/Mage/Catalog/Block/Category/View.php on line 159
