Ok, I solved the problem by applying this fix:
Change function : get_bloginfo_rss in wp-includes/feed-functions.php
function get_bloginfo_rss($show = ”) {
$info = strip_tags(get_bloginfo($show));
return convert_chars($info);
}
to :
function get_bloginfo_rss($show = ”) {
$info = ent2ncr(strip_tags(get_bloginfo($show)));
return convert_chars($info);
}
I applied this fix too, but it cannot solve my problem for rss ver. 0.92 though rss2 is working fine. It’s breaking at the HTML special character “&”.
