Ricky, you will need to enable DEBUG mode in config.php to find out what the real error is.
More info: http://www.oxwall.org/forum/topic/4661

ok

please my dev and debugging mode is on can u help me please www.campusghana.net

Ricky I will not be able to help you since the 500phtml error appears when you delete user from admin panel. And I don't have access to your admin panel.

You need to delete the user yourself. This time with enabled DEBUG mode you should get the real error instead of 500 one. Let me know what it is.

ok

Were you able to resolve this?

yes

I'm getting this problem also, received this message.

I cant delete user from admin and user cant delete their own profile

David, thank you for the report. I was able to reproduce this. Passed to development team.

Guys, error was caused by Privacy plugin.
We have updated "Privacy" plugin a couple of hours ago. New update of the plugin contains the fix to this issue.

go to ow_plugins/photo/bol/photo_service.php

find 635 line, 

there will be this code only:  OW::getEventManager()->trigger($event);

 replace it with try

{

        OW::getEventManager()->trigger($event);

}

catch (Exception $e){}

    }

in 1.6.1 the photo plugin will another logic and this fix will be deleted as you won't need it

This is not what I found on line 635. 

This is what I have on line 635:  * @param $hash       

However, I found a match on lines:  217, 1069, 1119, 1221, 1269 !

I still need help to fix that bug. 

Anyone can Help me ?

There should be this piece of code: 

 $event = new OW_Event('feed.action', array(            'pluginKey' => 'photo',            'entityType' => 'multiple_photo_upload',            'entityId' => $this->getPhotoUploadKey($album->id),            'userId' => $userId        ), array(            'photoIdList' => $photoIdList        ));

before this line: 

 OW::getEventManager()->trigger($event);

Outch ! 

When I try this, It crashed my site. Only getting a white page!

I have removed the changes :(

Georges, please PM me your admin and CPanel access details, I'll take a look at the problem.
