Bug: breaks the url if there is a : in it

Just FYI, the following code:

$ogurl = explode( ':', $ogurl);

will break the url in more than 2 parts, and therefore produce the wrong url:

// if url is, say https://www.somethig.com:8080/blah
$ogurl = explode( ':', $ogurl);
$ogurl_part = $ogurl[1];
$ogurl = 'http:' . $ogurl_part;
// The result is https://www.something.com

note that this is only a problem if the url has a : in it, which could be a port number or part of the query string in some cases.

A way to fix it would be to limit the explode:

$ogurl = explode( ':', $ogurl, 2);

which would split in at most 2 parts.
