Issues with integrated login and plugin User Switching

Hi!

Thank you for a great plugin. It seems to be amazing!

However, I am having problems with the integrated login. I am trying to use the User Mapping function to create new accounts on the forum for the WP-users, but I get the following message when doing so. I also get this message when trying to register on the WP-site as a new user or when I try to log out of the forum, or when I try to activate an account straight in the PhpBB ACP.

admin.php?page=wpu-user-mapper returned: Error: Invalid XML: Fatal error: Cannot redeclare validate_email() (previously declared in /storage/content/84/104584/mydomain.com/public_html/wp-content/plugins/wp-mail-smtp/wp_mail_smtp.php:350) in storage/content/84/104584/mydomain.com/public_html/forum/includes/functions_user.php on line 1749

Likewise, trying to login on the forum with one of the forum users that is not linked to any WP account doesn’t seem to work either and neither does logging out of the WP site, when this function is enabled.
Other weird things are happening too. For some reason once I am in the Admin and switch to looking at the actual site, I am logged out. This I think only happens in IE, although I am unsure if this is correct.

During the installation with Automod I had one instance where the following line could not be added automatically to memberlist-view.html:

<!-- IF U_BLOG_LINK -->
         <dt>{L_BLOG}:</dt> <dd><a href="{U_BLOG_LINK}" title="{L_VISIT_BLOG}" >{L_VISIT_BLOG}</a></dd>
      <!-- ENDIF -->

It should have been added after

<dt>{PROFILE_FIELD1_NAME}:</dt> <dd>{PROFILE_FIELD1_VALUE}</dd>
                <!-- ENDIF -->

And as that isn’t in the file, I instead added it manually after

<dt>{postrow.PROFILE_FIELD1_NAME}:</dt> <dd>{postrow.PROFILE_FIELD1_VALUE}</dd>
      <!-- ENDIF -->

Furthermore, WP-United also causes a conflict with a plugin called “User Switching” which simply seizes to function without error message.

Another factor in this might be the “slider” feature that the WP theme “Brunelleschi” has, which I am using to promote certain news items. This loads on the forum page, but not quite correctly. Functionally it seems OK, but I think the actual text is turned into the color black, which makes it unreadable against the background. However, the header for the news item is OK. The news item slide and roll just fine though.

Any advice on how this can be fixed other than disabling the plugin?

Thanks!
