The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

PHP issue causing router.php error in menu (SEF Link issue)...

Asked by EvinceUnlimited in PHP Frameworks, PHP and Databases, MySQL Server

Tags: joomla, database, mysql, router.php

Working on a joomla installation on a Linux server. Some nasty malicious code somehow made it onto my desktop which I normally have locked down tight. It attached itself to my ftp program, uploaded snippets of code to the joomla installation (on several domains actually). Well, I found every instance of code and can get into the back end now no problem. But when trying to access the front end of the site (which I had at the moment, put offline), I get this:

Fatal error: Call to a member function getDefault() on a non-object in /XXXX/XXXXX/public_html/XXXXXXX/includes/router.php on line 176

What is found on line 176 is:
$item = $menu->getDefault();

The Full Code of the router.php is attached in the code portion of this post. I was wondering if it was something in my sql database as I've tried just about everything on the Joomla install...
