'Page Not Found' error on all pages of Drupal website

I got page not error on all pages of a drupal website.

I solved this by running update.php

Soetimes this fixed navigation only. Clean urls will not work.
I found that .htaccess was corrupted. I transfered it again. It worked.
Finally I enabled clean URLS from my admin panel.

Setting cron job in drupal

Goto cpanel select cronjobs , you can see standard/advanced option.
Add this 'curl --silent --compressed http://yourdomain.com/cron.php'

Browse button not seen in tinymce

Add this function to template.php file in themes folder

/*
*Function for TinyMCE browse button
*/
function phptemplate_tinymce_theme($init, $textarea_name, $theme_name, $is_running) {
static $access, $integrated;

if (!isset($access)) {
$access = function_exists('imce_access') && imce_access();
}

$init = theme_tinymce_theme($init, $textarea_name, $theme_name, $is_running);

if ($init && $access) {
$init['file_browser_callback'] = 'imceImageBrowser';
if (!isset($integrated)) {
$integrated = TRUE;
drupal_add_js("function imceImageBrowser(fid, url, type, win) {win.open(Drupal.settings.basePath +'?q=imce&app=TinyMCE|url@'+ fid, '', 'width=760,height=560,resizable=1');}", 'inline');
}
}

return $init;
}
