BuddyPress.org

I have a few profile fields and I am trying to add more options to a dropdown field I have for Nationality, which has a list of countries, but when I save it gives me this message:

The link you followed has expired.

I search in WordPress and other people were getting the same message, but in other areas and for some it helped to update the php.ini values to have greater value, like this:

upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

But in my case it didn’t help, it seems like it has to do with Buddy press specific.

Can you please advice, thanks
