Regular users can not edit their profile - afer clicking Porfile / Edit profile (or other way) they got blank page, while joomla admin (SU) can normally see that page.
I have found an entry in apache log:
PHP Fatal error: Call to undefined function dom_import_simplexml() in /var/www/html/vw/libraries/joomla/form/form.php on line 857, referer: vw.testystron.pl/index.php/jomsocial
What have I missed in configuration?

vw.testystron.pl its for testing purposes set up site (fresh instance of joomla), user is test:test

Hi KRZYSZTOF,

That error because XML library not exist at your PHP configuration. please contact your hosting support to resolving 'Fatal error'.

Cheers,
Albert

Problem solved, I've added that library and script works fine.

Under CentOS it is: yum install php-dom
and restart apache.
