I'm trying to install the beta and getting the following
errors? any ideas? I'm on
Linux centos 2.6.18-8.1.8.el5
Apache 2.2.3

I'm getting this type of errors:
# Existing .htaccess found, merging in SilverStripe rewrite rules
# Building database schema...

mod_rewrite doesn't appear to be working. Make sure:

* mod_rewrite is enabled in your httpd.conf
* AllowOverride is enabled for the current path.

Please check these options, then refresh this page.If you believe that your configuration is correct, click here to proceed anyway.

What is "feature_turned_on"?

I set in the /etc/php.ini
error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR
used to be
error_reporting = E_ALL

and it seems to Install OK but the dev team might want to go through
and figure out why with warnings it fails. Probably the warnings set
a return code and the install scripts consider all non-success return
codes as failures.

Thanks
