I have no idea what's wrong and I don't know how to fix this. I've also tried another cash system and the same thing happens

That error is from a modification - to get rid of the error, disable the product and remove all files you added to the site to install it. If you need help with it, the place to ask is in the modification thread which is where you may get support.

Nevermind guys. I fixed it. I just added all files again and re-installed product
