I have a script that looks something like
$parent = Mage::getModel("catalog/category")->load(50);
$parent->setCustomUseParentSettings(false);
$parent->setCustomApplyToProducts(false);
$parent->setPageLayout("two_columns_left");
$parent->save();
And when I look at the category in Manage Categories
of the Admin, I can see that the values updated correctly, but when I look on the frontend, I see it's still using a different layout.
All I do then is click "Save" without modifying anything, and then it renders correctly on the front page.
I've tried reindexing Category Flat tables, but this is the only way I've been able to fix this. There's ~2000 categories so saving them all isn't a solution. How can I do this programmatically? Why doesn't it work in the first place?
