Customizing the colour theme and logo of Portal (using Community edition ) to suit the look and feel of our organization?

Though, I have read a few posts on how to achieve this using Community Edition of Bonitasoft, yet I have not been very successful in committing the changes. Every time we re-login from within Bonita Studio, we get the original BonitaSoft theme.

Kindly direct me on how to proceed with this in the Community Edition of the software?


Changing the look and feel of the portal, Subscription edition.

To whom it may concern,

I am trying to alter the look and feel of the Bonitasoft portal. The alteration is only to make the colour scheme blue and light blue. According to the page I only have to export the default look and feel, modify it and import it back into the portal. When I attempt to do this I get an error message, "An error occurred, please check your .zip file structure."
