It is including a PHP file that it should not be including, phpmailer. This is what is breaking things. </p> <p>PHPMailer is built into WordPress and is relied on by plugins that send email using the wp_mail() function. Themes and plugins shouldn't be including their own version, because it causes this error to occur if you do.</p> <p>See this screenshot of your themes functions.php file, notice the first require_once line in the code: <a href="http://grab.by/apU2" rel="nofollow">http://grab.by/apU2</a></p> <p>I went ahead and removed this line and the form is now submitting without any problems.</p> <p>These issues are common with themes purchased from ThemeForest because they are usually developed by theme developers that don't really understand WordPress development. They look pretty, but they are terrible under the hood. </p> https://legacy.forums.gravityhelp.com/topic/fatal-error-fatal-error-cannot-redeclare-class-phpmailer#post-28302 Wed, 22 Jun 2011 00:39:05 +0000 Carl Hancock 28302@https://legacy.forums.gravityhelp.com/ <p>Send us a WordPress admin login for your site as well as an FTP login and I can take a look and see what is going on so we can get it resolved. </p> <p>It's something specific to your site, but we can help you determine what it is and how to fix it.

When I go to test the form and I submit all the entries I get the following message:<br /> "Fatal error: Cannot redeclare class PHPMailer in /----/html/wp-includes/class-phpmailer.php on line 34"</p> <p>I can't seem to figure out this problem. I love this plugin and would love to keep it as long as it works. Please help me resolve this issue soon. </p>
