ah, the 'trick' for recreating seems to be changing the password...  then I can recreate...  this might be because nonces are no longer valid with a password change which may affect a user cookie... just a guess...   but now we can recreate and can investigate further...

so I can give you an easy fix for this...

find the file simple-press/forum/profile/forms/sp-form-accounts.php and edit it...  around line 20 find this code:

if (response.type == 'success') {
     spjDisplayNotification(0, response.message);
} else {

and change it to

if (response.type == 'success') {
     spjDisplayNotification(0, response.message); 
     window.location.reload();
} else {

this will force the profile page to reload when saving account settings since the wp nonces wont be valid after a user update with new passwords..

Great! That works. Thank you very much!

Will it still work after the next update? 🙂

Absolutely - the fix will be in the next release...
Thanks for the confirmation.
