Recovery Password Problem: no email send

[Danyx69]

Hi all,

I was on phpbb3 and i make the convert to vBulletin 3.8.4 patch level 2 .
Everything is ok but the 'recovery password' doesnt work .

I mean that i make 'recovery password', i put my email there and forum says that i will receive an email ... etc .
But i never receive that email, and nobody does

I try in myphpadmin with:

PHP Code:

UPDATE user
SET password='1234567'
WHERE usergroupid='2' 


And message confirm that i change the password for 4,221 users:

PHP Code:

4221 row(s) affected. ( Query took 0.0160 sec ) 


But no account have that 'changed password' (1234567) .

What is happend? What is the problem? Why my email doesnt work?
Is not from the webhosting, because i had vbulletin two months ago and everything wortks fine, and on phpbb3 to .. but now what should be the problem? Anyone ?

Kind Regards, Dany
