Title: Cannot install 4.6, “phpmailerException” error Last modified: September 2, 2016 --- # Cannot install 4.6, “phpmailerException” error * [bg17aw](https://wordpress.org/support/users/bg17aw/) * (@bg17aw) * [9 years, 9 months ago](https://wordpress.org/support/topic/cannot-install-4-6-phpmailerexception-error/) * This is for a new install, so it may be a WP core bug? * ``` Fatal error: Uncaught exception 'phpmailerException' with message 'Invalid address: wordpress@sitename.com' in C:\wamp\www\wp_test1\wp-includes\class-phpmailer.php on line 946 ( ! ) phpmailerException: Invalid address: wordpress@wp_test1.com in C:\wamp\www\wp_test1\wp-includes\class-phpmailer.php on line 946 ``` * I never had an error like this when setting up a new install before. * What I tried: – downloaded and installed successfully WP 4.2. This seem to enforce the idea of a bug in the 4.6 installation – upgraded 4.2 to 4.6 successfully. Strange.

Can you create a `phpinfo. php` file with this in it? * `` * And share that URL if possible?

Hard to believe there is something wrong there, but if you do notice something, let me know. * Like I said, older versions of WP install just fine.

The Apache2 part is fine but WordPress needs PHP 5.6 or later to work properly. * [https://wordpress.org/about/requirements/](https://wordpress.org/about/requirements/) * Can you update your WAMP to use PHP 5.6? PHP 7 works well if you can use that. * Thread Starter [bg17aw](https://wordpress.org/support/users/bg17aw/) * (@bg17aw) * [9 years, 9 months ago](https://wordpress.org/support/topic/cannot-install-4-6-phpmailerexception-error/#post-7722644) * That’s not actually correct, WP doesn’t require PHP 5.6, but PHP 5.2.4 (as per your link). * I don’t think this is the issue. * [KeyMaker](https://wordpress.org/support/users/keymakerproductions/) * (@keymakerproductions) * [9 years, 9 months ago](https://wordpress.org/support/topic/cannot-install-4-6-phpmailerexception-error/#post-8134734) * Upgrade WAMP just to make sure. You never know what new code in WordPress 4.6 is having problems with the older PHP 5.4.3. * Moderator [t-p](https://wordpress.org/support/users/t-p/) * (@t-p) * [9 years, 9 months ago](https://wordpress.org/support/topic/cannot-install-4-6-phpmailerexception-error/#post-8137010) * > WP doesn’t require PHP 5.6, but PHP 5.2.4 * That applies to “If you are in a legacy environment”… * > Note: If you are in a legacy environment where you only have older PHP or MySQL > versions, WordPress also works with PHP 5.2.4+ and MySQL 5.0+, but these versions > have reached official End Of Life and as such may expose your site to security > vulnerabilities. * Thread Starter [bg17aw](https://wordpress.org/support/users/bg17aw/) * (@bg17aw) * [9 years, 9 months ago](https://wordpress.org/support/topic/cannot-install-4-6-phpmailerexception-error/#post-8138576) * Hi Tara, The key here is `WordPress also works with PHP 5.2.4+ and MySQL 5.0 +` Let’s not confuse thousands of users using anything older than 5.6 by telling them WP won’t work. WP should work on 5.0+, security fixes are referring to PHP itself and not WP, and I am on 5.4 So not an issue here. * [AjitKhodke](https://wordpress.org/support/users/ajitkhodke/) * (@ajitkhodke) * [9 years, 8 months ago](https://wordpress.org/support/topic/cannot-install-4-6-phpmailerexception-error/#post-8212852) * It looks like your attempting to use a variable in the email address field of the Custom Email? * [oneumyvakin](https://wordpress.org/support/users/oneumyvakin/) * (@oneumyvakin) * [9 years, 6 months ago](https://wordpress.org/support/topic/cannot-install-4-6-phpmailerexception-error/#post-8448151) * I’ve get this issue at managing WordPress via wp-cli * The root cause in fact that $_SERVER[‘SERVER_NAME’] is empty in CLI mode: * \wp-includes\pluggable.php(352): PHPMailer->setFrom(‘wordpress@’, ‘WordPress’, false) * ``` if ( !isset( $from_email ) ) { // Get the site domain and get rid of www. $sitename = strtolower( $_SERVER['SERVER_NAME'] ); if ( substr( $sitename, 0, 4 ) == 'www.' ) { $sitename = substr( $sitename, 4 ); } $from_email = 'wordpress@' . $sitename; } /** * Filters the email address to send from. * * @since 2.2.0 * * @param string $from_email Email address to send from. */ $from_email = apply_filters( 'wp_mail_from', $from_email ); /** * Filters the name to associate with the "from" email address. * * @since 2.3.0 * * @param string $from_name Name associated with the "from" email address. */ $from_name = apply_filters( 'wp_mail_from_name', $from_name ); $phpmailer->setFrom( $from_email, $from_name, false ); ``` Viewing 9 replies - 1 through 9 (of 9 total) The topic ‘Cannot install 4.6, “phpmailerException” error’ is closed to new replies. * In: [Installing WordPress](https://wordpress.org/support/forum/installation/) * 9 replies * 6 participants * Last reply from: [oneumyvakin](https://wordpress.org/support/users/oneumyvakin/) * Last activity: [9 years, 6 months ago](https://wordpress.org/support/topic/cannot-install-4-6-phpmailerexception-error/#post-8448151) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
