Hey there, i have nuke 6.0 running but i have some problems. Here they are:

Everytime someone tries to register they don't get the e-mail with their password and they get this error message: Fatal error: Call to undefined function: mail() in /users/curvedspaces.com/jediclan/modules/Your_Account/index.php on line 119

Their account is created but they can't log in cause they didn't get the e-mail with the password.
It also happens with feedback or recommend us, both don't work.

Another problem i've found is this:
I can't validate my downloads, it gives me another error message. Like this: Fatal error: Call to undefined function: fsockopen() in /users/curvedspaces.com/jediclan/admin/modules/download.php on line 939

Hope someone can help me with this. Thank you very much.

Probably those two functions are disabled by your host, ask them to enable it or use the NSN Your Account Tweak wich allows you to let users show there own password so they don't need to receive an e-mail.
For the downloads I don't know a fix right away but I'll think of it

First of all thx for the reply.
I'm the host of it and i don't know where i can get that nsn your account tweak for nuke 6.0. I also have the same problem with feedback and recommend us, i also get the same error msg.

the nsn your account tweak is downloadable here http://www.nukescripts.net
