Wordpress Blogspot Tutorial

How to Change WordPress Search into AdSense Search

Jason wrote a very nice tutorial on how to turn the Wordpress Search box into Google AdSense search.

The tutorial is for a self-hosted Wordpress blog.

This is especially useful if your Wordpress theme has an embedded search box in the header. Instead of letting your visitors searching from the Wordpress search box, it's far better to let them search via Adsense Search box: it's more accurate and more profitable as well.

Remove W3 Total Cache Reinstall WP Super Cache

If you got RSS Feed error, most probable culprit is your WP Cache plugins. Removing it will get your blog back on track. There are other possibilities as well, such as blank/white spaces, etc.

So, I removed W3 Total Cache and Reinstall WP Super Cache

Visit this link to: Delete/uninstall W3 Total Cache

After almost three days of searching of what makes this blog's feed wasn't updating and been in error and googling of how to fix RSS Feed error, I finally found out the culprit: W3 Total Cache. It seems this great cache is not compatible with WP 3.1 of this blog.

So, I removed W3 Total Cache, and reinstall WP Super Cache.

Until W3 Total Cache is totally compatible with the latest wp version, I will not install it again.

RSS Feed Problems
Probable Root and Causes
How to Know the Problem
How to Fix the Error


I. RSS Feed Problem in Wordpress

Variation of error messages. The followings are some of them:

RSS Error: XML error: unclosed CDATA section at line 72, column 55
RSS Error: XML error: unclosed CDATA section at line 41, column 55
RSS Error - The feed could not be found
line 82, column 0: XML parsing error: :82:55: unclosed CDATA section
line 93, column 0: XML parsing error: :93:55: unclosed CDATA section
The URL does not appear to reference a valid XML file. We encountered the following problem: Error on line 82: XML document structures must start and end within the same entity -> this error message occur when you try to integrate the feed to Feedburner.


II. Probable Root and Causes

There is no single factor which might cause this RSS Feed error in wordpress. But Wordpress expert agree that at least these following factors may become one of the culprit:

Wordpress plugins: one or more Wordpress plugins you installed might cause the mess. In fatihsyuhud.com's case, it's W3 Total Cache which causes the RSS Feed error. So, I deactivate and delete it.
Blank space: a blank space in might cause RSS Feed error.
Bad themes: some themes incompatible with the Wordpress version you are using.
A bad post. a bad post is perhaps causing RSS feeds to not work correctly.
PHP being compiled without the curl option.
Others uncommon causes.

In my case, W3 Total Cache might be (not surely) the culprit. Particularly, if you enable the Minify setting. A Hostgator technician said:

The page appears to be minified, which is a process that removes unnecessary lines/characters from source code. Do you know what was used to minify this? It may have truncated the CDATA section.


III. How to Know the Problem

IV. The Solutions how to fix it

Check your wp-rss2.php and wp-atom.php files for blank lines outside of bracketed sections.
Check your wp-config.php file for blank lines outside of bracketed sections.
Check your theme's functions.php file for blank lines outside of bracketed sections.
One by one, disable plugins and revalidate until you isolate the one causing the problem.
If the above two points are not solving your problem, try one of these tips below:
Insert / comment the line in the function in wp-includes/template-functions-post.php file line 57 with the folowing code:// $content = str_replace(']]>', ']]>', $content);
Edit php.ini
Go to php.ini (ask your hosting administrator to setting your php.ini)
Search for "shell_exec"
Enable this function "shell_exec"
If the feed error is caused by a bad post, try to locate which post that cause the error and follow this tips everytime you write a post / article:

"Clean" copied text by pasting it into a plain text editor, such as Notepad (Windows) or TextEdit (Mac) and the copying the newly cleaned text before pasting it into your blogging application.

I. Why W3 Total Cache
My blog (not this one) got crushed two days ago because of sudden spike of visitors of around 65,000 pageviews a day. Actually, such number of visitors is still tolerable to Hostgator shared hosting so far as you have Wordpress cache installed. Unfortunately, I did not install it (as I did not expect the sudden rise of visitors). So, the CPU usage reaches between 26 to 30 percent. I breached the TOS 25 percent CPU usage. And the frontpage is disabled and cannot be accessed for a while.

Then came a letter of warning from Hostgator, which advise me to install W3 Total Cache which it said is the best among Wordpress cache plugins available.

Hostgator said: the plug-in W3-Total-Cache can be setup to provide sort of caching with the page caching method "Disk (enhanced)". Also, we would strongly recommend that you enable "Database Cache" and "Object Cache" in the plug-in's settings for the best performance.

II. About W3 Total Cache
