The Joomla! Forum ™

Hai everyone...

I've already read all the post about 404 - Component not found and try it to my web, but still doesn't working...

First, I open includes\application.php and edit file at line 124 :
if(!empty($component)){
$contents = JComponentHelper::renderComponent($component);
$document -> setBuffer($contents,'component');
}

Then, I open configuration.php and change :
var $live_site = 'http://www.mysite.com'

After that, I turned off all SEO setting :
/* SEO Settings */
/* var $sef = '0'; */
/* var $sef_rewrite = '0'; */
/* var $sef_suffix = '0'; */

But still, didn't worked out.
Please help me..
I've already try all the post, the error still same.

had a similar issue, came out to be an miss configuration by one of the team members, she deleted the mainmenu default home page ( accessible as "/" ) menu item ( Article -> Front Page ), and put an non existent url menu item as the default menu.

Thanks for the info...
I will try it soon...

My two cents,

I too was having the 404 component not found error, after moving from a blooded/slow Joomla installation to a new one. However, I was getting this error only when visiting a component directly(writing the address of the component in the address field of the browser) and not trough a link within the website.

PROBLEM:
In my previous installation I had a hidden menu that had all the links I wanted to use when I wanted some modules to appear only in some pages (menu items). So through my component I had the link/form to point at the alias of a hidden menu that did not exist in the new installation.

SOLUTION:
I created the old hidden menu and the problem was solved.

PS:
The solution proposed in this thread is not really nice, since when no component is specified the user will get the website without the component == no body == ugly!

I hope my problem/solution will help someone!

Sometimes the solution is in the most simple.

Go to "Global Settings" in your joomla, in "SEO optimization parameters and disable the option" friendly URLs for search engines "

Hope you can help with "error 404 Component not found"

I've change in the Menu Item Manager type of the default Menu Item from Article to Front Page and that works. I can use SEO and .htaccess

Hi Guys

Turning the friendly URLs helps indead but that is not the point. This function is there to be used and where I turn it on the '404 Component not found' problem comes back.

I've read it all and nothing helped.

Has anybody found what the problem is? Has Joomla released anything to fix that problem? A patch, an update?

I am using Joomla 1.5.18.

Thank You

I recently transferred over my Joomla site to another host. I checked the configuration page and everything seems to be correct. I am not using friendly URLs and nothing seems to work. I have the default main menu checked also. Have no idea whats happening. Please help.

Hi.

I recently move joomla web to a new hosting company.
Initially, i have the same error mentioned above.
Debugging the code,

file: /libraries/joomla/enviroment/uri.php at line 221~
method: base

is checked if php is configured like cgi. If so, the code use the var $_SERVER["PHP_SELF"] to get the base path.
In my case, with php 5.2.8 or 4.4.9 and apache 2.2.x, the return path is incorrect.
I need to disable this check and force to use the $_SERVER['SCRIPT_NAME'].
After that, all is working correctly without change anything else .

I don't now if this is really a bug and has been fixed in newer versions, suppose... yes (my is 1.5.13).

By.

hi guys
I am using Joomla 1.5.18. This issue gave me big headache until i set my SEF in my global configuration to no. Thnx a lot guys. However, I am still unable to install new components and modules to my joomla. It works fine on my local host but i gives me problems on the online one. Any ideas?

thankx in advance........

I DO NOT WANT TO TURN OFF THE SEF URLS!... I SHOULDN'T! I NEED THE SEF URLS for SEO reasons!... urgh!... there HAS to be a solution! i've read all 3 pages, and no one has a solution to this matter!... :S

it's weird no one has been able to pin point the source of this problem!

and my case has neither to do with default menu, nor coding!... im sure it's a server side issue, coz i've been working on it for the past 5 days!... i give up!... damn! :S

Another solution, is to go to Control Panel>Global Configuration>SEO Settings

There mark NO in "Search Engine Friendly URL"

That's work for me.

Good Luck!

Sometimes System - Backlink plugin will cause trouble to the component link. When I enable System - Backlink, all links to my component either direct to main page or failed to work. Just disable System - Backlink plugin and everything is back to normal again.

Another reason for such a heinous situation would be simply because you're not running on a dedicated Linux server... you might be running on a Hybrid Windows server which would have a PHP library, and you CAN install Joomla! on it... everyting would go well, until you activate the mod_rewrite for the .htaccess file

hai


I try to write administrator component coding and create zip file and install into version joomla 1.6 component after install my components are missing any help

Hello and welcome!
Let me tell you that I do not understand a thing but for the fact that you are trying to install Jooml;a 1.6 and you have an issue with that. If so you should post in the Joomla 1.6 forum and not in the Joomla 1.5 forum. You also need to describe what issues you are facing with what environment you install and what errors you get

You may not be able to visit this page because of:

1. an out-of-date bookmark/favourite
2. a search engine that has an out-of-date listing for this site
3. a mistyped address
4. you have no access to this page
5. The requested resource was not found.
6. An error has occurred while processing your request.

Please try one of the following pages:

* Home Page

If difficulties persist, please contact the System Administrator of this site.

tell how i get my content on website again.
my content is there in administrator , but not showing that content in my website.

so tell me what i do to get that content on my website.

I've had the same problem after updating akeeba backup.

everytime I try to install an item I get

404 - An error has occurred.

Component Not Found

ALOOOOOOHAAA !!!
And Greetings From Hawaii !

First post - I registered just to post this. Hopefully it brings some sanity to others that run into the same problem.

I too had the dreaded “404” - “Component not found” on the index.php page. BUT every other page worked properly. I just spent 5 hours fingering this out and trying one thing after another, most of the suggestions in these threads.

I have to agree with Nibinaear when he says that Joomla should really handle such a core component better. or throw up some red alert warning message like “your about to F up your website by deleting the primary menu index link.”

My problem was : I am editing a site, and there are 2 menus on the site. The nice one on the very top, and one crappy one on the right side. So i deleted the crappy one on the right side. Turns out... THAT one was “Main Menu.” I did not notice the problem at first because every other page in the site continued to work.... until i hit “HOME” to go to the main page. then BOOM ! 404

NO amount of adjustments from within the administrator section made it work again. To make it work, I had to follow farkow's post and edited the database itself using phpmyadmin.

His “Important points” section is what tipped it off for me. I had a menu link to the main domain name, but it was not what it needed to be. Here are my modified setting suggestions.

Log into your database and look at your *_menu table. Search and see if you have your "home page" linking with :
"index.php?option=com_content&view=frontpage"
If not, then change the data of these 3 fields :


I changed those 3 data fields and the the site is working again.. without a “main menu” and instead a user defined “top menu”

Hello all, I was having the same problem when i installed a custom module and it turned out to be a simple fix of a stupid overlook.

It was a naming convention problem.

the component folder was named: com_darts
the php files were named darts.php
but the <menu> and <name> in the xml was Dart Management

as soon as I changed the xml items to darts it fixed the problem.

hope this helps, it will at least give some of you a place to start looking.

Hello,

I just wanted to share the fact that I had a Error 404: Component not found when I tried to view my site on my localhost (using WAMP, migrated from Joomla 1.5 to 1.7 using Jupgrade).

The weird thing was that I could access the backend of my site but not the frontend.

After much heartache and research (google, WAMP and joomla forums) where I tried a number of solutions (including changing the port for Skype) I realised that I had accidently removed the "star" to indicate that the "Home" menu item was "Home". I reinstated this and everything works fine.

I hope this will help someone else.

Kind regards,

Joyce

I am sure that this is not as complicated as some of the posts I have read. Here goes.

I changed page titles for some of my pages and when I previewed them they showed up fine so I saved them. The problem is now every page I have amended gets the dreaded 404 error and worse still is that google now shows them as 404 errors.

I am told this is a permalink error and that I need to change the permalink of each page changed.

Need help with this URGENTLY before I lose the google rankings for the pages.

Many Thanks

I encountered the same problem, and was able to resolve this by editing the $live_site value in configuration.php, to my domain name.

source: joomla doc

I'm having a similar problem except mine only happens when I try to view the page via a mobile phone, when I check the website from my PC I have no problem. I've used both an Android and iPhone and both have this issue. Any suggestions?? I'm new to Joomla as well.

I have the same problem here after moving my onine website to my localhost.
i get 404 error for the main pages. i found that in the main menu default and in its menu item type there is no article item to be chosen. usually we it should be featured article and other article type but now there is nothing!! i have not solved it yet and i would be glad if anyone can help
