Strange... I already posted this, but it disappeared... deleted by moderator for some reason???

Joomla: 1.5.1
CB: 1.1
Browser: Firefox 2.0.0.12
OS: MacOS 10.4.11

Reproduction Steps:
1) Install CB 1.1 on Joomla 1.5.1
2) Configure to use CB user registration
3) Browse to new user registration form on site
5) Fill out registration form and enter a valid password starting with a number: 1234abcd
6) Click 'Send Registration' button

Error:
Validation error message pops up indicating that the password is invalid, even though the password is actually a valid password.

I am having this same issue. Have you found a solution to it?

For those folks not able to move to CB 1.2 in the near future, the following is a potential fix to the problem of not allowing a numeral as the first character of the password:

if you look at /components/com_comprofiler/comprofiler.html.php. There are two occurrences where a regular expression is used to validate the password (there is a third for the username which you should ignore). You can easily find the two occurrences by searching for "checkJversion". The first two occurrences that are found are the ones to change. The third one that you find is related to the username and is in a javascript function called "cbSendUsernameCheck".

The expression that is broken is as follows:
[code:1]
var r = new RegExp("^[a-zA-Z](([\.\-a-zA-Z0-9@])?[a-zA-Z0-9]*)*$", "i"«»);
[/code:1]

To allow a 0-9 to be entered at the beginning of the password, change the line of code to this:
[code:1]
var r = new RegExp("^[a-zA-Z0-9](([\.\-a-zA-Z0-9@])?[a-zA-Z0-9]*)*$", "i"«»);
[/code:1]

If you google "regular expressions php", you can identify ways to modify this expression further to allow other characters like !, #, $, etc.

Another thing to note is that you might want to change the error message string that is displayed when the user enters an invalid password.

This can be done by modifying the file /components/com_comprofiler/plugin/language/default_language/default_language.php. Search for the keyword "_VALID_AZ09".

This problem still exists in 1.2.1 at least in my 1.2.1

logged into the back end as super admin and have the field set to no-validation.

min length 5 chars.

won't take 5 digit number...

CB 1.2 is hard-coded to take no less than 6-character passwords. You can change it to require more, but not less.
