+       This could be the result of one of our Apache directives not being 
+supported by your version of Apache. Examine your apache server logs.
+       You might remove the line "Options -Indexes" from the .htaccess file if 
+you are using a Windows server as this has been known to cause problems.
+Also check your file permissions. Your website and all contents must generally 
+be world-readable.

+
+       First check your file permissions. Your website and all contents must 
+generally be world-readable.
+
+       Ensure that mod-rewite is installed and working, and that your
+.htaccess file is being used. To verify the latter, create a file test.out
+containing the word "test" in the top directory of Friendika, make it world 
+readable and point your web browser to
+
+http://yoursitenamehere.com/test.out
+
+       This file should be blocked. You should get a permission denied message.
+
+       If you see the word "test" your Apache configuration is not allowing
+your .htaccess file to be used (there are rules in this file to block access
+to any file with .out at the end, as these are typically used for system logs).
+
+       Make certain the .htaccess file exists and is readable by everybody, then 
+look for the existence of "AllowOverride None" in the Apache server 
+configuration for your site. This will need to be changed to 
+"AllowOverride All".  
+
+       If you do not see the word "test", your .htaccess is working, but it is 
+likely that mod-rewrite is not installed in your web server or is not working.
+
+       On most flavour of Linux,
+
+% a2enmod rewrite
+% /etc/init.d/apache2 restart
+
+       Consult your hosting provider, experts on your particular Linux 
+distribution or (if Windows) the provider of your Apache server software if 
+you need to change either of these and can not figure out how. There is 
+a lot of help available on the web. Google "mod-rewrite" along with the 
+name of your operating system distribution or Apache package (if using 
+Windows).
