.htaccess
On the root level you may need to define that the default file is the index.php
/.htaccess
DirectoryIndex index.php
To have simple URL you can add the following:
/.htaccess
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?name=$1 [L,QSA]
You can then enable it in the configuration file $swSimpleURL = true;
Sofawiki installs automatically .htaccess files for inc/, site/ (deny from all) and exceptions (allow from all) for inc/skins/, site/cache, site/files/ and site/skins/. Note that the main .htacess file remains manual.
