Unable to create an e-mail account in ISPConfig

[onastvar]

I am unable to create an e-mail account in ISPConfig. After I click save and I did fill out all the fields including the name I get the following error message:

The following error occurred:

Field: Real Name
Only the following signs are allowed: a-z A-Z 0-9 - _ .

CentOS 5.1 with ISPConfig Ver: 2.2.23

[till]

As the error message states, you have a not allowed character in the name field.

[onastvar]

I entered the following when i was creating new account

Real Name: jamie
Email Address: jamie@mydomain.com
Username: web5_jamie
PasswordL jamie

I think, I used allowed characters.

Also when I am on the ISP user screen where I create an new account I get same error message if I click on tabs Advanced Settings & Spamfilter & Antivirus

The following error occurred:

Field: Real Name
Only the following signs are allowed: a-z A-Z 0-9 - _ .

[onastvar]

I was able to resolve issue

Field: Real Name
Only the following signs are allowed: a-z A-Z 0-9 - _ .

by reinstalling ISPConfig 2.2.23
