I am using v0.9.1 of the RSS footer plugin, and I have my RSS footer set to:
%%POSTLINK%% is a post from: <a href="http://domain.com">My Site</a>
When viewing the RSS feed, POSTLINK is correctly changed to the post title/url, but there are still percentage signs around it.
I think there's a bug in the plugin, and line 143 of the plugin should be changed from:
$rssfootcontent = str_replace("POSTLINK",$postlink,$rssfootcontent);
$rssfootcontent = str_replace("%%POSTLINK%%",$postlink,$rssfootcontent);
Thanks very much.
