Ok, I found a hack.

In components/com_comprofiler/plugin/user/smf_profile.html.php

Around line 290 find:

            <?php
            if ($context['member']['email_public']) {
                ?>
                <a href="mailto:<?php echo $context['member']['email'];?>" title="<?php echo $context['member']['name'];?>"><?php echo $context['member']['email'];?></a>
                <?php
         //   } elseif (!$context['member']['hide_email']) {
                ?>
                <i><a href="mailto:<?php echo $context['member']['email'];?>" title="<?php echo $context['member']['name'];?>"><?php echo $context['member']['email'];?></a></i>
                <?php
            } else {
                ?>
                <i><?php echo $txt[722];?></i>
                <?php
            }
            ?>

and comment out the elseif statement like I have

I'm having the same problem. To eliminate the display of email addresses I've unpublished the SMF Profile plugin for CB.

Great job Ryan, thanks!

I agree this post should be a sticky!

Should also go in to Joomla-SMF Forum Configuration and set the Registration System and Login Module to CB.

Just ignore everything below. It was that VirtueMart eCommerce Edition of Joomla 1.0.12 that I installed. I just replaced the index.php with the one from the regular Joomla 1.0.12 and patched it and now everything looks OK.

Joomla: 1.0.12
PHP Version: 4.4.3
MySQL: 4.0.24

SMF: 1.1.2
CB: 1.02

All files from JSMF_2_0_2_unzip1st.zip downloaded from this forum
com_smf_2_0_2.zip
cb_plug_smf_2_0_3.zip
cb_plug_smfinfo_2_1_1.zip
cb_plug_smfposts_2_1_1.zip
cb_plug_smfprofile_2_1.zip
cb_plug_smfprofile_2_1_1.zip
cb_plug_smfsignature_2_0.zip

When attempting to patch file in Joomla-SMF Forum Installation:
Failed: Code to be patched not found in file:$message = intval( mosGetParam( $_POST, 'message', 0 ) );/mypath/to-my/server/docs/index.php

Closest I can find in my index.php is:

if ($option == 'login') {
    $message = mosGetParam( $_POST, 'message', 0 );
   $mainframe->login();


Using CB-Login I get these errors
When logging in: Incorrect username or password. Please try again.
After clicking OK to close the error box I'm logged in.

When logging out: The requested URL /action=logout&sesc= was not found on this server.

I have to log out using the log out button on the user menu.

Login-Logout problems go away if I unpublish the cb_plug_smf_2_0_3 plugin in CB

User is not automatically logged in to SMF in either case.

Just noticed, when trying to view any CB profile all I get is "Hacking attempt"

I know it must be me doing something wrong!
OK, if I unpublish ALL of the SMF plugins for CB, viewing profiles works again.
 

Installed on Mambo 4.5.2.1

This those 2 radio buttons to select to use Mambo or SMF login. I think selecting the Mambo button and saving still works because it gets saved in the configuration file.

Registration module to use:
