I need the character & in the username

Hello

So I modified 3 file in joomla core so now I can register username with character & in user admin of joomla.
But now I still have the same problem in CB user management when I try to register user with &, same error before "Please enter a valid Username:. No spaces, more than 2 characters and contain 0-9,a-z,A-Z"

I think now I have to do something in CB but what??
Can You help me please :blush:

Thanks
Frank

In field management I set Authorized input: Custome Perl regular expression and in Perl Regular Expression: I wrote /^.*$/
But still not change, I really dont know what to do anymore

Any suggestion :blush:

Not sure what to tell you.
Perhaps you have not modified (aka HACKED) Joomla correctly and the API call made by CB to Joomla is failing.

This is just not supported in Joomla and in CB as it will break SEF on username profile links.
