I have added links to my cms pages in menu bar(about-us, contact-us, gallery).
And created url rewrite(type=custom) with url rewrite management option in magento admin panel.
Its works fine. But after some time url rewrite changes the type to system and Target Path Url rewrite upgrade themselves automatically.
type = system
Target Path = catalog/category/view/id/158
And give messages like product not found in this category.
I am creating url rewrite using url rewrite management daily 2-3 times and deleting those automatically created.
I am searching for a permanent solution
Please help me
