2 WP Installation

Hi,

I have 2 WordPress Installation configured as follows:

1) domain.com
2) domain.com/tata

They are completly seperate installation.

The problem: when the plugin is activated on both sites, 1) domain.com results randomly to a blank page.
2) domain.com/tata/blog/post/url -> redirects to -> domain.com/blog/post/url which results to a 404 error.
actually missing the “tata” in the url.

I think i’m facing the same problem in this previous topic: http://wordpress.org/support/topic/plugin-w3-total-cache-w3-total-cache-crashing-with-multiple-installs
