jQuery( ‘input#signup_with_blog’ ).click( function() {
jQuery(‘div#blog-details’).fadeOut().toggle();

== in the groups and members button, the buddypress apparence seem too high … ==

You can add something like the following to your stylesheet:
`div#content { margin-top: 20px; }`

== you can try to clic on the ”test” button, it does’nt work anymore ==

The “test” page on your site was working when I checked it before we did Step 3 of the compatibility process. Checking it now.
