Internal Server Error on 1and1 after Drupal 7 deployment

It's an OpenEntreprise distribution with many enabled modules, si I thought it was the php memory_limit set up at 90M (max. for 1and1).


After reading the Drupal forum (, I found out that the rewrite base in my .htaccess should have been uncommented. Even this setting caused no problem on my local installation.

# If your site is running in a VirtualDocumentRoot at,
# uncomment the following line:
RewriteBase /
