Hi Henry,
During the last hour I had a problem with my WP admin key. I corrected it. And yes, I’m logged in.
I found a configuration error after reenabling BP. I can now create new topics and change profile picture. But I can not create new groups even as administrator.The problem remains and it is not a theme issue.

[Marisa]

Yes, Henry. The problem remains with Twenty Fifteen too.
Please, see this screenshot:

No “create new group” option appears neither “create new topic” in the forum page.
The same thing with Fourteen and with Mantra.

Hi Henry,
Using fourteen the problem remains. I think it is not a theme issue.

[Marisa]

Yes, Paul. Please, take a look:
I’m logged as admin. Here the Activity page:

and here the Groups page:

No “create new group” option or button appears
neither “create new topic” in the forum page
I have switched back the theme to “Mantra” because the site looks very bad with 2014, as @djsteveb suggested. All the plugins disabled except BP.
Before the upgrade to WP 4.1, BP was working very well. BP was integrated with s2Member plugin (now disabled) that was the core of my membership site.
Thanks for your assistance.

Thank you very much Paul for your help.
Unable to create new groups after WP 4.1 upgrade because the option does not appear to create a new group or create new topics or to change the profile image, even to the admin.
There are only two groups created before the upgrade.

@djsteveb – I disabled all the plugins; I have reenabled only BP, I have switched back the theme (2014) and BP is still not working.
I have no folder like /mu-plugins/ and no file like bp-custom.php inside the WP content.
I dont know how to go on…
Thank you very much for your assistance!

I have just solved this problem by replacing parts of the default bp-core-functions.php archive where it says “function bp_core_time_since”
I used parts of this file: https://svn.buddypress.org/tags/1.6-RC1/bp-core/bp-core-functions.php
