Hi there,

I'm a semi newb to silverstripe and have had a great experience so far working with the platform. I have successfully loaded silverstripe onto a few different servers for various projects, but have come across an issue after having a client request to use Telecom as their webhost.
During installation I'm getting the warning that mod_rewrite has not been enabled - I've searched through the forum on similar issues but so far have not found a definitive solution.
Having been in touch with Telecom on this they assure me that mod_rewrite is enabled on their system and that the problem lies in my .htaccess file (for which they provide no support).

Here is the .htaccess file as it currently sits (fresh at install):

### SILVERSTRIPE START ###
<Files *.ss>
   Order deny,allow
   Deny from all
   Allow from 127.0.0.1
</Files>

<Files web.config>
   Order deny,allow
   Deny from all
</Files>

ErrorDocument 404 /assets/error-404.html
ErrorDocument 500 /assets/error-500.html

<IfModule mod_alias.c>
   RedirectMatch 403 /silverstripe-cache(/|$)
</IfModule>

<IfModule mod_rewrite.c>
   SetEnv HTTP_MOD_REWRITE On
   RewriteEngine On

   RewriteCond %{REQUEST_URI} ^(.*)$
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteRule .* sapphire/main.php?url=%1&%{QUERY_STRING} [L]
</IfModule>
### SILVERSTRIPE END ###

Here is also the latest message from Telecom's support desk:

"We support making sure that mod rewrite is working, but we do not support the syntax of a .htaccess file. That falls under the purview of coding.

Looking at the error log for the site shows that this is not an issue with mod_rewrite, but is an issue with an infinite loop written into the rewrite code. Fixing that should allow for the use of mod rewrite.

See below in www/logs/error_log:

A solid solution would be much appreciated - pretty much at a loss here....

Thanks in advance!

I am having the exact same problem - different provider though. Are there any ideas on solving this? Furthermore, is it safe to continue the installation and remedy this afterwards?

Issue is with index.php
There is a line where a string comparison is done without taking into account of the different separators for windows and linux.
Change the following line
   $fileURL = (dirname($_SERVER['SCRIPT_NAME'])=='/'?'':dirname($_SERVER['SCRIPT_NAME'])) . '/' . $url;
to
   $fileURL = (dirname($_SERVER['SCRIPT_NAME'])==DIRECTORY_SEPARATOR?'':dirname($_SERVER['SCRIPT_NAME'])) . '/' . $url;
and that should solve your problem.
