This plugin creates security risks and spams code

I owe even a pro version, but I still see my source code (HTML output code) spammed.
This also exposes security risk for hackers, who will search for vunerable version or plugins all over the internet.

This is the notes how to manually remove the spam and security risk from your plugin:

1. Edit this file:
\wp-content\plugins\all-in-one-seo-pack-pro\aioseop_class.php

2. FIND: “<!– All in One SEO Pack Pro” code, and replace the section with the following:

// GOOD DEVELOPER EDIT: COMMENT THE SPAM & VULNERABILY EXPOSURE OUT
/*echo "\n<!-- All in One SEO Pack Pro $this->version by Michael Torbert of Semper Fi Web Design";
if ( $this->ob_start_detected )
	echo "ob_start_detected ";
echo "[$this->title_start,$this->title_end] ";
echo "-->\n";
echo "<!-- " . __( "Debug String", 'all_in_one_seo_pack' ) . ": " . $aioseop_update_checker->get_verification_code() . " -->\n";
*/

3. Find the ‘<!– /all in one seo pack pro’ code part, and replace the section with the bellow:

// GOOD DEVELOPER EDIT: COMMENT THE SPAM & VULNERABILY EXPOSURE OUT
//echo "<!-- /all in one seo pack pro -->\n";

4. Now your WordPress website in spam-aware and more secure.

5. If you don’t do this (steps 1 to 4), you will see this spam and security risk in your website HTML OUTPUT CODE:

<!-- All in One SEO Pack Pro 2.3.6.1 by Michael Torbert of Semper Fi Web Design[{DOWNLOADS-COUNT}] -->
<!-- Debug String: {PREMIUM-PURCHASE-CODE} -->
<meta name="description" itemprop="description" content="{SOME RANDOM WORDS}" />
<link rel="canonical" href="http://{DOMAIN_URL}/" />
<!-- /all in one seo pack pro -->

6.If you do the steps 1 to 4, then you will have the clean HTML code in same place, and HTML will only outputs these lines:

<meta name="description" itemprop="description" content="{SOME RANDOM WORDS}" />
<link rel="canonical" href="http://{DOMAIN_URL}/" />

Have a good use :).
