Typo in system_advanced_admin.php, service_snmp.php and interfaces.php?

[_igor_]

Configuring System: Advanced: Admin Access, on saving settings an HTTP-port-error appears like "htmlspecialchars… on line 264".

Looking this line its like this:

I changed class="formfld unknown"to ```
class="formfld"

hmmm, same thing happens on interfaces.php. Lots of```
class="formfld unknown"
```and with every line with this code inside an error appears in the reflecting page.

same on service_snmp.php.
