Hi, problem is coming from the javascript validating the form. It cannot handle bad-formatted strings for showing the warnings.
To solve that :
Check you language file (french, dutch have the same problem) between these tags (around lines 761 -> 777):
/** registration.php */
and
/** classes/html/registration.php */
File : components\com_comprofiler\plugin\language\[language]\[language].php
What you must check is :
- Quotes are not correctly escaped and defined('_VALID_AZ09') is not correclty %'ed.
What I see is that the profile update still not works after that change (but registration does).
I'll look after it now and post an update after fixing it.
