But as soon as I uncomment the line in local/config.php where it says:

$PageLogoUrl = "..."

nothing works any more. No page is displayed. I had thoght of something
like this:

$PageLogoUrl = "$PubDirUrl/skins/myskin/images/Logo.png"

or alternatively:

$PageLogoUrl = "http://localhost/pub/skins/myskin/images/Logo.png"

which definitely both do not work.

Now I have made a workaround.

In the new skin I have changed the line in the .tmpl file such that it
now reads:

<div id='wikilogo'>
 <a href='{$ScriptUrl}'><img src='$SkinDirUrl/images/Logo.png'
  alt='$WikiTitle' border='0' /></a>
</div>

This works perfect. So I personally have no problems.

But it's kind of funny though...

  $PageLogoUrl = "http://localhost/pub/skins/myskin/images/Logo.png";

Second, the $PubDirUrl variable may be yet undefined early in config.php, so
if you use it, it is recommended to do either:

  $PageLogoUrl = "\$PubDirUrl/skins/myskin/images/Logo.png";

(inside double quotes, a backslash \ will not allow for the variable to be
expanded at this point, it will be expanded later in the skin) or:

  $PageLogoUrl = '$PubDirUrl/skins/myskin/images/Logo.png';

(inside single quotes, variables are not expanded, so this one will be
expanded later in the skin).

Now, the "second" part is for your specific case, it may be not adapted for
another case. I can recommend reading a little about the PHP programming
language in order to get comfortable with the strings and variables.

The "semicolon" part can be used in other cases.

I recently tried to modify our wiki page using edit, but can't be saved.
It always shows message like this:

We are sorry for any inconvenience.
