Insert , Update Back buttons not working when creating/updating product

[Guest]

I am fairly new to php coding, but have learned alot since installing over 30 contributions on my website. While installing one of my contributions, I must have coded something wrong. I'm not sure which file I was in nor contribution, but now when I try to add a new product or update the product, the buttons at the bottom seem to not work. I thought these might be in the Catalog.php file, but I have compared my current version to all previous versions and they look the same. Do the buttons at the bottom of the product page point to a particular file? How can I go about troubleshooting the reason these are not working?

 

Thanks!
