 * In browser (Opera, Explorer, Chrome) when I placed order i see QR code that i
   can click. But the link looks like : [http://bitcoin](http://bitcoin) adress..
   
   In the settings i see also: <a href=”//{{{BITCOINS_ADDRESS}}}?……… and the most
   interesting fact that i see <a href=”//{{{BITCOINS_ADDRESS}}}?…….. in gray field
   next to field that i can change..??
 * But it should be: <a href=”bitcoin://{{{BITCOINS_ADDRESS}}}?
 * I am trying to add “bitcoin:” before //{{{BITCOINS_ADDRESS}}}? in settings but
   it disappear after i save it. ???
 * In bwwc-bitcoin-gateway.php i see correct line <a href=”bitcoin://{{{BITCOINS_ADDRESS}}}?…
   and I have ho idea how is it cuted and by whom.
 * Any ideas?

 * I’m having this same issue. I tried changing it in the file and on the page, 
   but it keeps stripping out “bitcoin” in the href section. I’m not sure if this
   is a WordPress thing or this plugin.

 * Aha! I think I found the problem. WP limits allowed protocols in their clean_url
   function. You can disable the function or add the bitcoin protocol!

 * I was able to change it on WordPress 3.5.2 by changing line 3749 of wp-includes/
   functions.php to:
 * `$protocols = array( 'http', 'https', 'ftp', 'ftps', 'mailto', 'news', 'irc','
   gopher', 'nntp', 'feed', 'telnet', 'mms', 'rtsp', 'svn', 'tel', 'fax', 'xmpp','
   bitcoin' );`
