So, I am updating some images on the left side of the website (dog-a-holics.com) I added in the category tree another category - specifically Dog ID Tags. I've edited the index file which is named index.new.html. However, it's not showing up.
I noticed that the site main page keeps going to index.php. If I go to dog-a-holics.com/index.new.html it shows the update (specifically the tag titled "Dog ID Tag").
I am not understanding why this is happening. I am taking over the mess that was left to me from a previous employee and I'm not 100% website savvy.
Is there a reason why a .php file was used?
