I am using Nucleus as my CMS for my website. However, I would like to display only my News category by default when a visitor comes to my website. The default now is of course index.php but I would like to change it to index.php?catid=1&blogid=1 to display the news instead of the content. Any idea how to implement this?

Add a condition to index.php to redirect to the required version if catid or blogid is empty

If I do that won't I be creating a loop such that every visitor will be redirected to the category? Nucleus don't work using many pages, the CMS only have index.php. The content is based on the different categories.

only if the value is empty, if it has a value there will be no redirect
