no confirmation email for registration!!!!!!!!!!

Hello,
I'm using CB 1.4 and Joomla 1.5.15, I use the connection modul of community builder, I half also:
Requires the consent of the administrator: NO
Requires confirmation e-mail address: Yes

but when a new user registers, he does not receive the confirmation email!
I found that this subject was proposed but with the previous version of CB (Version 1.2), I tried these solutions but the problem still persists!
Can someone help me! is very urgent ...
Regards,
Chaker

nobody has the solution!!!!?????

Welcome to our forums.

Please refrain from using !!!!!!!!!! in title - it is perceived as yelling.

Back to your issue.
Please upgrade to Joomla 1.5.23 as your environment is old and could have issues.

Also before posting please read our FAQ articles.

Specifically test that your Joomla Mass email is working. If it is not then any component trying to send email from your website will have issues also.

Hello,
Thank you for your quick response,
No I do not cry Mr. Nick, I just wanted an answer as I have been looking for a long time, I'll try your proposal and get back to you
Regards,
Chaker
