installation went fine, but 2 probs with configuration

[mstock]

hello ispCP-Fans,

i just installed the new 1.0.3-1 on Ubuntu 8.04 Server
and everything seems ok. it's possible to add resellers
and users, databases and email-accounts.

but i'm not sure how to adjust the configuration files,
as there still remain 2 problems:

1)
the pma can not load the mcrypt-extension, and setting
$cfg['Servers'][$i]['auth_type'] = 'http';
in the /var/www/ispcp/gui/tools/pma/config.inc.php
also did not help, as then pma constantly shows the login-popup

2)
in the htdocs-directory of the new domain it's possible to create
custom-named html- and php-files and to call them in a browser.
but when i delete the standard index.html and place an index.php
instead of it, nothing happens.

i have mod_rewrite enabled, cause i later want to install drupal.

"ls -l mods-enabled/ | grep rewrite" gives:
lrwxrwxrwx 1 root root 30 Dec 26 17:25 rewrite.load -> ../mods-available/rewrite.load

and "cat mods-available/rewrite.load" gives
LoadModule rewrite_module /usr/lib/apache2/modules/mod_rewrite.so

is it possible that mod_rewrite can cause such a strange behaviour?

if anyone has any suggestion, i would really appreciate...

thx,
michael
