The mail was send including the attachments. Based on the error message it might be also an attachment that can’t be parsed for email messages. Do you tried to add different attachements? Please let me know how this worked for you. * Plugin Author [Areeb Majeed](https://wordpress.org/support/users/areebmajeed/) * (@areebmajeed) * [7 months, 1 week ago](https://wordpress.org/support/topic/php-fatal-error-484/#post-18703724) * It seems like the issue is related to this piece of block: * ```wp-block-code 230 if (!empty($attachments)) {231 $payload['attachments'] = array();232 foreach ($attachments as $key => $attachment) {233 $payload['attachments'][] = array(234 'file_name' => basename($attachment),235 'content_type' => mime_content_type($attachment),236 'content' => base64_encode(file_get_contents($attachment)),237 'inline' => false238 );239 }240 } ``` * [@finalwebsites](https://wordpress.org/support/users/finalwebsites/) Let’s add an if statement here checking if the attachment is valid or not. * ```wp-block-code if (!$attachment) { continue; } ``` * Thread Starter [Leonidas](https://wordpress.org/support/users/visionoptika/) * (@visionoptika) * [7 months, 1 week ago](https://wordpress.org/support/topic/php-fatal-error-484/#post-18703980) * Hello * I have something else to add in my first post. The problem appears only when I turn the order to completed by clicking the complete button inside the admin orders’ list and not when I do the same from the admin product page * [https://prnt.sc/RFInnzWaZzOy](https://prnt.sc/RFInnzWaZzOy) * I also checked two different situations. With or without upload an attachment. Every time I see the same php fatal error. * Hope I helped you somehow * Leonidas - This reply was modified 7 months, 1 week ago by [Leonidas](https://wordpress.org/support/users/visionoptika/). - This reply was modified 7 months, 1 week ago by [Leonidas](https://wordpress.org/support/users/visionoptika/). * Plugin Author [Olaf Lederer](https://wordpress.org/support/users/finalwebsites/) * (@finalwebsites) * [7 months, 1 week ago](https://wordpress.org/support/topic/php-fatal-error-484/#post-18704008) * Thanks for the additional information. In the mean time I did also more tests and I got finally the same errors you got. In my first test, the PDF invoice plugin was still active. After deactivation I got similar errors.Based on this, I added some validations to avoid the fatal errors. I will publish a new plugin version within the next hour.For your own case I suggest to use a different solution, because the class script is doing something wrong. And that’s why the error occurs inside the Maileroo mail function * I’m not saying your solution is bad, but it could be better. The problem you’re having today could also arise tomorrow with a different feature. Furthermore, your solution requires installing a plugin that hasn’t been updated in two years. Perhaps this plugin would work for you? * [https://wordpress.org/plugins/woo-product-attachment/](https://wordpress.org/plugins/woo-product-attachment/) Viewing 5 replies - 1 through 5 (of 5 total) The topic ‘PHP Fatal error’ is closed to new replies. * ![](https://ps.w.org/simple-smtp-by-maileroo/assets/icon.svg?rev=3131913) * [Simple SMTP by Maileroo](https://wordpress.org/plugins/simple-smtp-by-maileroo/) * [Frequently Asked Questions](https://wordpress.org/plugins/simple-smtp-by-maileroo/#faq) * [Support Threads](https://wordpress.org/support/plugin/simple-smtp-by-maileroo/) * [Active Topics](https://wordpress.org/support/plugin/simple-smtp-by-maileroo/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/simple-smtp-by-maileroo/unresolved/) * [Reviews](https://wordpress.org/support/plugin/simple-smtp-by-maileroo/reviews/) * 5 replies * 3 participants * Last reply from: [Olaf Lederer](https://wordpress.org/support/users/finalwebsites/) * Last activity: [7 months, 1 week ago](https://wordpress.org/support/topic/php-fatal-error-484/#post-18704008) * Status: not resolved
