Title: Site crashed Last modified: September 9, 2022 --- # Site crashed * Resolved [wpfiend](https://wordpress.org/support/users/wpfiend/) * (@wpfiend) * [3 years, 7 months ago](https://wordpress.org/support/topic/site-crashed-47/) * Hello. I have been using this plugin for some time now with no issues. Just updated it and crashed my site. Had to SFTP into the backend to delete the plugin to get my site back up. Everything is up-to-date on the site, except the WordPress version, 5.9.4. (We cannot update WordPress for a little while as we need to update all our custom code first.) Thanks in advance.

The only reason that you may have issues are if you have an older version of the PHP (less than 7.4). * I’ve checked the plugin on version 5.9.4 of WordPress – with no errors. Can you please check your php – and check if it’s PHP 7.4 or higher ? * If your PHP version is lower than 7.4 i would suggest you use the older version of this plugin. * Please let me know. - This reply was modified 3 years, 7 months ago by [digamberpradhan](https://wordpress.org/support/users/digamberpradhan/). * Thread Starter [wpfiend](https://wordpress.org/support/users/wpfiend/) * (@wpfiend) * [3 years, 7 months ago](https://wordpress.org/support/topic/site-crashed-47/#post-15995928) * Appreciate the fast response. * Yes, the older PHP version could very well be the culprit. * Will you please send me a link to the previous version of your plugin, as it was working fine on my site…?? * Thanks in advance. * Thread Starter [wpfiend](https://wordpress.org/support/users/wpfiend/) * (@wpfiend) * [3 years, 7 months ago](https://wordpress.org/support/topic/site-crashed-47/#post-15996369) * Actually, I just checked, and we are using PHP version 7.4.15. * So, it must be something else within the plugin then. * Plugin Author [digamberpradhan](https://wordpress.org/support/users/digamberpradhan/) * (@digamberpradhan) * [3 years, 7 months ago](https://wordpress.org/support/topic/site-crashed-47/#post-15996575) * Hey again, * You can get the previous version of the plugin from the development tab. [https://wordpress.org/plugins/woo-preview-emails/#developers](https://wordpress.org/plugins/woo-preview-emails/#developers) * Also, i’m running the same configuration on a brand new / clean site without any errors, can you please let me know what the error log is showing you ? * Thread Starter [wpfiend](https://wordpress.org/support/users/wpfiend/) * (@wpfiend) * [3 years, 7 months ago](https://wordpress.org/support/topic/site-crashed-47/#post-15996762) * Hi. I will take a look at the error logs and report back here. Also, I tried to get the previous version of the plugin from the Development tab but did not see a link to it. Can you please send me a specific link to the previous version…??

Soon as the plugin was updated ? Previewing an e-mail template ? * Thread Starter [wpfiend](https://wordpress.org/support/users/wpfiend/) * (@wpfiend) * [3 years, 7 months ago](https://wordpress.org/support/topic/site-crashed-47/#post-16016474) * Hi. * For me, it was as soon as the plugin was updated. * [Michael Sumner](https://wordpress.org/support/users/xmic/) * (@xmic) * [3 years, 7 months ago](https://wordpress.org/support/topic/site-crashed-47/#post-16019725) * It is the same for me as soon as the plugin has been updated then it causes a critical error. If it helps I was on Bedrock on PHP 7.4.30 WP 6.0.2 * Plugin Author [digamberpradhan](https://wordpress.org/support/users/digamberpradhan/) * (@digamberpradhan) * [3 years, 7 months ago](https://wordpress.org/support/topic/site-crashed-47/#post-16022382) * With PHP 7.4 and above it should in theory not cause any problems if the variable is defined as either null or instance of that class. * [@xmic](https://wordpress.org/support/users/xmic/) can you please try uninstalling and re-installing the plugin to test it out again. I have tried downgrading – and the updating the plugin many times on version PHP 7.4 and i’m not able to recreate the issue as of yet.
