I have had various issues navigating my wiki seemingly because $base_url is not getting built correctly, or at all. The first of these issues happens at login where the user puts in a bad username or password. The redirect to the error page fails on Firefox and has a URL with doubled forward slashes after the domain because the $base_url is not getting passed. URLs get built as follows (where 'example.com' is my domain):

Firefox:

http://example.com\/tiki-error.php?error=Invalid+username

IE:

http://example.com//tiki-error.php?error=Invalid+username

This happens with relative URLs all over tikiwiki in my installation, which is a WAMP with virtualHost entries in the httpd.conf to resolve 2 distict domains on the same server.

So far the only partial solution I have found is to add the $base_url declaration to the template page header, like so:

<script>
        function define_baseurl() {
             $base_url = "http://example.com"}
    </script>

This is a partial solution as it does not resolve issues where I add RSS feeds via a module to a page (as these apparently get built with relative rather than absolute URLs).
