I can access the PHP file itself, but when requesting anything with "GET variables?", it gives the following error:
this might be happening because x10hosting's free-hosting servers - use [ mod_security ] to help protect users websites - it will automatically block any "suspicious" requests, to help prevent common attacks and spam bots.
mod_security settings will throw a 404 error if it sees a "leaky" response and a 403 error if it sees a "shady" request
you'll get either a 403, a 404 or an empty response instead, depending on the apparent severity
I have changed the folder's permissions to 755 and 644
make sure all file permissions are 0644 (rw-r--r--) and all folder permissions are 0755 (rwxr-xr-x)
IF 'permissions' set on any folder or file - in your account - are [ 777 ] - that makes a large security risk - so a x10hosting's free-hosting server will throw an immediate "Access Denied" (403 error code) error to protect itself
