Weird. Can't delete records from database all of sudden.

[man5]

So here I was trying mkdir function with 0777 permissions.  Everything worked fine.  However when it came to delete the images in the directory, it won't let me.  I have a 404 error page set up and it takes me to that page after i click delete. 

 

I had a backup of the this project before i added mkdir.  So I went back to it and it's still taking me to the 404 error when deleting an image. While on 404 page; in the address bar, it's still shows the id of the file to be deleted. For eg. http://localhost/project/delete.php?id=199

 

Can someone explain to me what is going on?

LOL! Found the problem. I renamed my delete.php file and forgot to update it in upload.php. Silly mistake. It's all good now.
