I was messing around with functions.php and my site went blank. I must've added or deleted something. I can't remember. Now I can't access anything. I can't get to the login page to get to my site or to do administrative work.
I'm not that great with wordpress or website building or design. I was trying to make some changes to a theme that I've purchased and installed and now I can't access anything.
I need help. I've tried looking at my server bluehost but don't even know what to look for there and I've read through several posts but I'm getting more confused. How can I access my page to fix this and perhaps reinstall the theme?
