Title: Plugin causes downtime. Last modified: September 21, 2023 --- # Plugin causes downtime. * Resolved [Vadoh](https://wordpress.org/support/users/vadoh/) * (@vadoh) * [2 years, 8 months ago](https://wordpress.org/support/topic/plugin-causes-downtime/) * Hi there, I’ve been using this plugin for years and it works fine, but two days ago, I started experiencing downtime. I disabled all themes and plugins on my website and re-enabled them one by one where I found out Simple Download Monitor Plugin is the one causing the downtimes. * I received a mail from WordPress stating the errors below; * Error Details =============An error of type E_ERROR was caused in line 348 of the file /home/rmfpp/public_html/rmfpp/wp-content/plugins/simple-download-monitor/ main.php.

Are you running the latest version of our plugin? * Kind regards. * Thread Starter [Vadoh](https://wordpress.org/support/users/vadoh/) * (@vadoh) * [2 years, 8 months ago](https://wordpress.org/support/topic/plugin-causes-downtime/#post-17070898) * I didn’t change anything on my server or the website, I even disabled all plugins and left SDM enabled to check if a random plugin is conflicting with SDM and it turns out the issue is from SDM itself. I use the latest version of the plugin. * Plugin Contributor [mbrsolution](https://wordpress.org/support/users/mbrsolution/) * (@mbrsolution) * [2 years, 8 months ago](https://wordpress.org/support/topic/plugin-causes-downtime/#post-17071050) * No one has reported an issue like this. Something has happened in your site or server. What PHP version is running in your server? Can you also disable and delete our plugin. Then install and activate a fresh new copy. * Kind regards. * Thread Starter [Vadoh](https://wordpress.org/support/users/vadoh/) * (@vadoh) * [2 years, 8 months ago](https://wordpress.org/support/topic/plugin-causes-downtime/#post-17071504) * I use PHP 8.1.23, I’ve deleted and reactivated a fresh copy of the plugin, it’s still the same thing. Sometimes, it will act normal maybe after reactivating and will start causing downtimes again. * If I disable the plugin without deleting, the website works well and fast. But after activating, reverse is the case. * And things are not like that before. Can you list out what I can do? * Plugin Contributor [mbrsolution](https://wordpress.org/support/users/mbrsolution/) * (@mbrsolution) * [2 years, 8 months ago](https://wordpress.org/support/topic/plugin-causes-downtime/#post-17073057) * Can you check your server log files? Also, can you elaborate further what do you mean by downtime? I want to make sure I understand your issue correctly. * Thank you. - This reply was modified 2 years, 8 months ago by [mbrsolution](https://wordpress.org/support/users/mbrsolution/).
