skins preview in Preferences is buggy

[RadoS]

Moin,

while experimenting with the Preferences page I tried to preview some skins, but the server returned some php errors, couldn't include something or some variables missed their values.
If you can't reproduce, come to #cpc channel on IRC.freenode.net, see Links page, then we can do it together

Hello - most probably, the same that causes most problems; we're waiting for the server to be updated to a current PHP version. On the other hand, I just tried previewing the other day, and it works fine!?

Despite the error-msg I chose to use "classic" skin, and this is what I get on each page now:

Notice: Undefined variable: underline in /var/www/vhosts/cpcwiki.eu/httpdocs/includes/Skin.php on line 375 [and line 380]

Other skins might have had other/ additional errors.
