The problem has come back after a few hours although the web server shows .htaccess under the web directory and ht.access under the manager directory... Is there something else you would do to solve it once and for all?
The below is the content of the .htaccess file under the web directory:
# For full documentation and other suggested options, please see
#
http://svn.modxcms.com/docs/display/MODx096/Friendly+URL+Solutions
# including for unexpected logouts in multi-server/cloud environments
# and especially for the first three commented out rules
#php_flag register_globals Off
#AddDefaultCharset utf-8
#php_value date.timezone Europe/Moscow
Options +FollowSymlinks
RewriteEngine On
RewriteBase /
# Fix Apache internal dummy connections from breaking [(site_url)] cache
RewriteCond %{HTTP_USER_AGENT} ^.*internal\ dummy\ connection.*$ [NC]
RewriteRule .* - [F,L]
# Rewrite domain.com -> www.domain.com -- used with SEO Strict URLs plugin
#RewriteCond %{HTTP_HOST} .
#RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
#RewriteRule (.*)
http://www.example.com/$1 [R=301,L]
# Exclude /assets and /manager directories and images from rewrite rules
RewriteRule ^(manager|assets)/*$ - [L]
RewriteRule \.(jpg|jpeg|png|gif|ico)$ - [L]
# For Friendly URLs
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
# Reduce server overhead by enabling output compression if supported.
#php_flag zlib.output_compression On
#php_value zlib.output_compression_level 5
