please reply to mt topic thank you.

Here is the full error message

[Wed Oct 07 09:29:19 2009] [error] [client 01.234.153.101] PHP Fatal error:  Function name must be a string in /home/mysite/public_html/inc/classes/BxDolProfileFields.php on line 348, referer: http://mysite.com/join.php

[Wed Oct 07 09:29:19 2009] [error] [client 01.234.153.101] PHP Parse error:  syntax error, unexpected T_STRING in /home/mysite/public_html/inc/classes/BxDolProfileFields.php(346) : runtime-created function on line 1, referer: http://mysite.com/join.php

Unfortunately, none of those error messages reference a field name.  Has it ever worked?  It is a long shot, but if you happen to remember the last field you added you could remove it and see if that is causing the problem.

You have probably added a new items on Builders/Fields Builder -> Join Form

Click on the item you have made and choose Advanced and delete what you have added inside the box Check:

Check about you need to correct this on Edit Profile - View Profile - Search Profile also.

(Be sure you use it correct if you add some specific check here, PHP-expression, usually is not needed anything here)

Thank you very much I did what you say and it fix the problem
