string offset trouble

Hi there,
We’ve been using UM for over a year on a forum site and all went well untill this week.
Now, when adding a new user and clicking submit, we get a blank page with a lot of this:

Warning: Illegal string offset ‘form_id’ in /home/www/mydomain/www/wp-content/plugins/ultimate-member/includes/um-short-functions.php on line 943

Notice: Uninitialized string offset: 0 in /home/www/mydomain/www/wp-content/plugins/ultimate-member/includes/um-short-functions.php on line 943

and this:

Fatal error: Uncaught Error: Call to undefined function bp_is_active() in /home/www/mydomain/www/wp-content/plugins/bp-registration-options/includes/core.php:130 Stack trace: #0 /home/www/mydomain/www/wp-includes/class-wp-hook.php(288): bp_registration_options_bp_core_register_account(145) #1 /home/www/mydomain/www/wp-includes/class-wp-hook.php(312): WP_Hook->apply_filters(NULL, Array) #2 /home/www/mydomain/www/wp-includes/plugin.php(478): WP_Hook->do_action(Array) #3 /home/www/mydomain/www/wp-includes/user.php(1897): do_action(‘user_register’, 145) #4 /home/www/mydomain/www/wp-admin/includes/user.php(230): wp_insert_user(Array) #5 /home/www/mydomain/www/wp-admin/user-new.php(163): edit_user() #6 {main} thrown in /home/www/mydomain/www/wp-content/plugins/bp-registration-options/includes/core.php on line 130

After that, I get an email about a new member suvscribtion, with a link and I can go to the overview and voila, the user is there…
Same thing happens when I delete a candidate user from that overview: it gives a lot of errors…

Hope you can help!

Thanks
Bye
