Fix XML parsing Failed Error WordPress : Blame PHP
Actually, it is PHP which is responsible for this error. The possibly the best solution is to add this things :
---
1 2 3 | $out = ob_get_contents(); $out = str_replace(array("n", "r", "t", " "), "", $input); ob_end_clean(); |
to wp-includes/feed-rss2.php (and/or other Feed generating PHP files like that for comment). As we have root access, we edited the file on nano text editor going to the root of WordPress installation :
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | nano wp-includes/feed.rss2.php # Editor <?php /** * RSS2 Feed Template for displaying RSS2 Posts feed. * * @package WordPress */ header('Content-Type: ' . feed_content_type('rss-http') . '; charset=' . get_op$ $more = 1; // We have added from here $out = ob_get_contents(); $out = str_replace(array("n", "r", "t", " "), "", $input); ob_end_clean(); // here it ends ! echo '<?xml version ="1.0" encoding="'.get_option('blog_charset').'"?'.'>'; ?> <rss version="2.0" xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:wfw="http://wellformedweb.org/CommentAPI/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" // no need read the whole file! |
We just saved the file. Well, it worked. There are lot of Feed related PHP files like feed-rss2-comments.php, feed-rss.php, feed-rdf.php, feed-atom.php, feed-atom-comments.php etc. but this one is for what we get as Post feeds. We have modified the previous how to do steps in this update :
