I've deployed a sample Opencart2.0 under a subdirectory in my godaddy domain. I've created a OCMod xml file remove_unused_desc_from_category.ocmod.xml
which removes a line from <sub_dir>/catalog/view/theme/default/template/product/category.tpl
I've installed this using Extension Installer and refreshed the cache. Then checked the new file <sub_dir>/system/modification/catalog/view/theme/default/template/product/category.tpl
which had the change.
But it is still not affecting the UI. I'm still a learner of opencart and OCMod. Kindly help.
