Hello.
It sounds strange (and I don't know it's related with J! or JS), but one of my site's superuser reported that he can't change password with frontend. And I replicated it too with another account:
1) login as superuser "support".
2) navigate to profile page and press "Edit Profile" button.
3) type twice new password to "Password" field.
4) Save changes. Message appear that everything is OK.
5) logout
6) try to login using new password
Result 1: Site display error message (wrong autorisation)
7) try to login using OLD password
Result 2: Logging success.

Everything works OK if try the same with "registered" user.

P.S: If you will get success with changing password for "support" (superuser), can you please inform me (send me new password) by any way (for example posting it to "Require help from Admin/Mod" area)?

P.P.S: Users also reported that problem appears befor updating to JS4.4.

Thanks.

HI, Dmitry.

Thank you for contacting us.
Super User password can't be changed or recovered at frontend due to security issues :)
The only option to change SU password is backend.
That's a Joomla! principle ;)

Hi. Thanks you. :)
I know that it's impossible to recover password but didn't know that it also impossible to change password in frontend too.
When I press "Save changes" button, it display Message that everything is OK. This message generates by JomSocial? May be it should display some extra text "Everything is OK, exept changing password" (if user is in suoerusergroup)?
Thanks.

HI, Dmitry.

Notice is a general one and form do not distinguish between admin and common user password change attempt.
From form point of view all is ok but password change requests are just nulled by Joomla! itself.

Hello. I also noticed that super user can’t change his RealName in frontend (in JS 4.3 everything was OK).

When I press "Save changes" button, it display Message that everything is OK. But profile still display old name.

HI.

SU account can't by modify in frontend :)
Please, do not mix topics :P

Hello. I just tested standart Edit Your Profile Joomla's option and it allw to change realname at frontend.
And it was able before in JomSocial. Now JomSocial doesn't allow to do it.

Thanks.

HI.

I just tested this at my site and I was able to change real name of Super User.
It seems that this is your site specific issue.
I'll assign developer to take a look.

HI, Dmitry.

The issue not related with JomSocial.
It's caused by System - Admin Tools plugin. that plugin prevent super user to edit the login detail from frontend, security reason.

Here the steps:
1. turn off System - Admin Tools plugin from joomla plugins manager
2. clear joomla cache
3. goto frontend as super user
4. edit the account from jomsocial
5. save it

result:
super user will able to changing the password
