Joomla Mod Rewrite & 500 Errors – Problems and Solutions

Friday, February 26th, 2010

The time always comes in a web developer’s life when they are working on a redesign or upgrade of an existing site. This is generally a more rewarding project, as the knowledge gleaned from the lifespan of the existing site provides much valuable information for the new development. This is also a double edged sword as we must also be careful not to upset our existing search engine visibility and all old pages must be redirected to new pages.

This is achieved through the use redirection and issuing the HTTP 301 status code which indicates the resource has moved permanently.

URL Rewriting with Joomla!

If you are moving to a Joomla! site or simply updating the structure of an existing Joomla installation then you will need to dive into the murky world of URL rewriting with .htaccess. Things are a little more tricky if you are using Joomlas search engine friendly URL system as you have to be careful not to upset any of the existing rules so knowing what you are doing can (and will) save you a whole bunch of headaches.

If you are not using the URL rewriting system in Joomla! then you will need to add a .htaccess file and simply add your mod rewrite rules. If you are looking to add rules to an existing Joomla .htaccess file then you will need to be a little more careful.

Adding Rewrite Rules to Joomla .htaccess

The Joomla.htaccess file is clearly marked up showing three distinct areas. You want to place your rules after the block that is commented as ‘Rewrite rules to block out some common exploits’ and before the block that is commented ‘Begin – Joomla! core SEF Section’.

The following shows where are new rules are to go, the exact text may be slightly different or there may be additional comments but this should help you identify correct place to add your new rules.

########## End – Rewrite rules to block out some common exploits

########### new rules go here

# rewrite oldpage1.html to site root

rewriterule ^oldpage1\.html$ / [R=301,L]

# rewrite oldpage2.html to newpage.html

rewriterule ^oldd-page.html /newpage.html [R=301,L]

########### new rules end here

########## Begin – Joomla! core SEF Section

Common Problems – Joomla 500 Error

There are lots of other.htaccess problems that can generate the dreaded 500 internal server error. Things vary between different web server configurations so there are no concrete answers but the following are some of the most common problems and solutions.

1. Options +FollowSymLinks

Try adding or removing this line

2. RewriteBase /

If you rules are causing problems, try adding or removing ‘RewriteBase /’

3. L = Last Rule

Always make sure your 301 rewrites include the optional L flag ([R=301,L]) to indicate that this is the last rule.

On a more general note, if you have problems then comment your rewrite rules, un-comment them one at a time and test till you find the culprit. Nine times out of ten you will find that your problem lies in small error in the syntax or at the very least by identifying the exact problem you can request or search for targeted help.

Better now?

Mod Rewrite is a powerful tool but the syntax can be confusing and troublesome for casual users. Combine that with the general purpose 500 internal server error and you have a recipe for confusion and lost time.

What Are the Reasons of Computer Shut Down?

Thursday, February 25th, 2010

Anyone who has been around computers a lot will definitely experience its shutting down. There are dozens of reasons why a computer shuts down and each reason stems from a whole lot of PC issues. If one want to avoid it then it’s better to know first what kind of shutting down is going on.

There can be several factors that can cause a computer to shut down automatically. Virus is one of the factors that could have corrupted the system files and device drivers. If this happens, then the PC would have to be started on safe mode by using the administrator account. The system will need a scan by using anti-virus software to diagnose and remove the infected files. Other problems that can cause a PC to automatically shut down may be overheating, due to dirt and dust or the power supply.

If the computer shuts down because of overheating, it can be prevented by applying thermal gel over the CPU. This gel will not cause the machine to short circuit but it is safe to use and effective in keeping the computer’s internal temperature low. If the PC shuts down because of dirt and dust, then its fan needs to be checked if it is working properly.

The fans blades have to be checked and a blower, soft brush or vacuum cleaner can be used for cleaning the dust. If the reason if power supply, then maybe there is a loose plug from the power supply or it could be that a required and proper power voltage regulator is not being used and the electric current has been randomly fluctuating in the area. It’s better to stop using the PC temporarily in this situation because random power fluctuation can damage the PC’s power fuse.

For troubleshooting the problem of computer shutdown, the issue has to be resolved by following some steps. The PC has to be started first and then the Control Panel has to be opened. Performance and Maintenance icon has to be clicked. Power Options has to be clicked and then the APM tab. The box of Enable Advanced Power Management Support should be checked and then clicking the OK button.

An advanced configuration power interchange is present in some computers that shows completed message on the screen before the PC shuts down. It its not there, then the one that has a HAL should be used; it is installed in computers that support APM only. The ones without this do not turn off even when they are shut down. PCs with ACPI have an ACPI-compliant BIOS that allows the PC operating system to turn off its power supply automatically.

These causes are not wide range and there may be other many reasons that can cause a computer to keep shutting down. Finding the real cause can take some time. It will be much better to get a professional’s opinion on how best to fix the problem.
