World writeable access to httpdocs directory while running PHP
Under Net24's PHP hosting environment, PHP does not run as an Apache module, but instead runs under suexec mod_fcgid. For security suexec mod_fcgid does not permit the document root to be world writable. If your httpdocs permissions show the following...
```
drwxrwxrwx  10 user  group  512 Oct  1 11:54 httpdocs
```
..you then have world writable permission set on the directory. The permissions should be as per below (chmod 750):
```
drwxr-x---  10 user  group  512 Oct  1 11:54 httpdocs
```
The permissions can be changed using the Plesk File Manager.
