Problem:

railer (in Joomla forum) says:

Hi,

I’m trying to install version 1.5.1 and after solving what I’m pretty sure were permissions issues, I got the installer to run. I’ve deleted the installation directory I tried to go to the Home page, but only saw a blank white page. Same thing happened when tried to go to the Administrator area. Now, when I go to the Home page, I’m getting the following 404 component not found error page:
——-
404 Component Not Found

Call stack
# Function Location
1 JSite->dispatch() /home/path/to/siteroot/index.php:68
2 JComponentHelper->renderComponent() /home/path/to/siteroot/includes/application.php:124
3 JError->raiseError() /home/path/to/siteroot/libraries/joomla/application/component/helper.php:123
4 JError->raise() /home/path/to/siteroot/libraries/joomla/error/error.php:173
5 JException->__construct() /home/path/to/siteroot/libraries/joomla/error/error.php:138
——-

I’ve no idea what to do now. Never encountered this before when doing Joomla installs. I think this is being generated by my server control panel (ServerCP). Do you think the files are corrupted?

Thanks in advance for any help offered,
railer

PS: I had been running version 1.5 RC3 before on this server. Then I deleted the site files and dropped all tables from the DB and then did a clean install of 1.5.1 using a quickstart version from Joomlart.com.

and fix by Farkow:

You can also get that error if you change the default menu item type.
You need to edit some values in your database (for example open phpmyadmin)
Create a menu or edit the default menu like below;
(These values are my default settings)

menutype = mainmenu

name = Home (whatever yours)

alias = home (whatever yours)

link = index.php?option=com_content&view=frontpage

type = component

published = 1

parent = 0

componentid = 20

sublevel = 0

ordering = 1

checked_out = 0

checked_out_time = 0000-00-00 00:00:00

pollid = 0

browserNav = 0

access = 0

utaccess = 3

num_leading_articles=1

 num_intro_articles=4

 num_columns=2

 num_links=4

"

lft = 0
rgt = 0

Important points;
menutype = mainmenu
link = index.php?option=com_content&view=frontpage
type = component
componentid = 20

Best wishes…
