Switched from iPage to GoDaddy now my website is a mess

I have a website that I consider as a hobby and so I went with the cheapest web hosting which was iPage. Once my year was up with them I moved over to GoDaddy a month ago, because they were going to be about half the price. I used the migration tool with GoDaddy but now my website is a mess. It randomly works and doesn’t work (mostly doesn’t work) and I’m too much of a noob to figure out what the problem is. I’ve been struggling with this for a month now trying to figure it out. I have access to the myPHP (though I’m a noob at it) and my FTP through my FTP client. Can anyone help me figure it out??? My domain is: https://definitivegamedates.com
