–You must update your permalink structure to something other than the default for it to work—
Hi,
Feel stupid, but no idea what is aked: after downloading buddypress and before it wil work I have to change the permalink structure, but the url of my site is recognized,

my question is to which site I have to change the standard link: http://new60/new60/???????????

Try updating your permalink settings here:

Choose anything but the default.

Thanks, in the permalink it are frozen urls, so I did a lot of other things, .htacess code and so on. As this is a website on the same account of another website, the provider gave more space and then I started from scratch again, brand new website (not a big problem as the site was from yesterday)

After installing buddypress: the same notification…error. Grrrt, then I only changed in permalinks the choice from -default- to -custom- and, amazing, that solved the problem.

So thank you, it is solved.
