Scriptrunner (Doug Sparling)

If you know the ID of the post, you can just call this in page.php (or whatever template you’re using for your page):

<?php
$id = 78;
$my_post = get_post( $id );
echo $my_post->post_title;
echo "<br />";
echo $my_post->post_content;
?>

I’m guessing you only want to add this to a single page, so you might want to create a separate template specifically for this page, or check for the page ID in the page template.

The username and password for what? wp-config.php contains the username and password for your database. What ever is in wp-config will have to match your database credentials (or at least one of theme, usually it’s best to have a separate database login for your web app). If you are indeed updating the username and password for your database, you’d update that most likely in cPanel that your web host provides. (I’m assuming that, since you mentioned control panel)

If you do have DEBUG set to true, then setting it to false is about all you need to do. Unfortunately, a lot of plugins will display warnings if DEBUG mode is set to true. This is different from an error (or at least a fatal error). For security reasons, it’s best to never run a production site with DEBUG set to true. Good luck!

Warning: strlen() expects parameter 1 to be string, object given in /home/content/60/10837160/html/ugometrics/web/wp-includes/formatting.php on line 1820

This is a warning, not a fatal error. This also suggests that you are probably running your production site with DEBUG set to true.

One thing you’ll want to do if that’s the case is change

define('WP_DEBUG', true);

to

define('WP_DEBUG', false);

in wp-config.php.

Next item, it only appears to be happening to a single user’s comments, so you might look in the wp_comments table and see if there’s something odd about his record. The warning is saying that WordPress expects $email to be a string and it isn’t.

Finally (or firstly), you should try temporarily deactivating all plugins and changing to a default WordPress theme like TwentyThirteen to see if the problem persists (the Safe Mode plugin is handy for that if you don’t want to do it manually).

I installed the “dinky” theme on a vanilla WordPress 3.6.1 install and I’m not seeing that the function that the code you posted is in is even being called, which makes me wonder if a plugin or theme is involved.

I was able to duplicate it, and the plugin causing the problem in my case is:

WP Facebook Open Graph protocol

FYI – WordPress caches feeds for 1 hour, so you may need to update a post to have it refresh your feed.

Later today I’m going to dig through the plugin and see why it’s causing the issue.

Let me know if deactivating that plugin does or does not fix your feed.

Take a look at this Codex page:

Function Reference/query posts

One example on that page may get you started:

query_posts( 'cat=1&tag=apples+oranges' );

though you may not need the category id…

Every time someone’s RSS feed breaks, it’s always because of additional content added to the feed. In the cases that I have been able to track it down, it was always because of a plugin.

I see this at the top of your feed:

<script type="text/javascript">

  var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-27424618-1']);
  _gaq.push(['_setDomainName', 'knolzone.com']);
  _gaq.push(['_trackPageview']);

  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
  })();

</script>

<!-- Woo Tabs Widget -->
<script type="text/javascript">jQuery(document).ready(function(){var a="#tagcloud";var b=jQuery("#tagcloud").height();jQuery(".inside ul li:last-child").css("border-bottom","0px");jQuery(".wooTabs").each(function(){jQuery(this).children("li").children("a:first").addClass("selected")});jQuery(".inside > *").hide();jQuery(".inside > *:first-child").show();jQuery(".wooTabs li a").click(function(a){var b=jQuery(this).attr("href");jQuery(this).parent().parent().children("li").children("a").removeClass("selected");jQuery(this).addClass("selected");jQuery(this).parent().parent().parent().children(".inside").children("*").hide();jQuery(".inside "+b).fadeIn(500);a.preventDefault()})})</script>

<!--wp_footer-->

so something is adding footer html to your feed xml.

You’ve already indicated the disabling all plugins fixes this, and as I said, I’ve always found the cause to be plugin. (though in theory, it could be a theme – you might try switching to default theme like TwentyThirteen to see if anything changes)

I’d really like to be able to duplicate this. Could you post a list of all the plugins you are using?
