Sorry to hear you have issues activating the plugin. First, that error seems strange since we are not able to reproduce it on any server before. From the above error – it looks like the plugin is missing some files that results to plugin activation error. * Can you please try the following steps to see if it works for you? - Prime Mover works for PHP 5.6+ – if you are using a server below PHP 5.6, you cannot activate the plugin and it throws an error. So you need to upgrade your PHP version first to supported versions (_PHP 7.4_ is recommended minimum for WordPress now). - In addition – if you are using supported PHP versions but still have an error. It’s possible you are using a corrupted version of the plugin. In this case– please re-install again using different method. First, we try the manual method of installation – [download the latest Prime Mover plugin zip to your Desktop](https://wordpress.org/plugins/prime-mover/). Click the “_Download_” button to get the latest zip to your Desktop. - Next is to delete all the Prime Mover plugins existing in your _/wp-content/ plugins/_ directory. To make sure they are all deleted – you can double check with SFTP or FTP to delete it. - Before you install it again – double check with your hosting tech support if they do a real time file scanning of uploaded files. It is because these file scanners could result to false positives and will mistakenly delete plugin files while it’s being installed. As a result – installed plugins are corrupted when any of it’s file is deleted. We recommend to temporarily disable these real time file scanners to test. - When it’s clear that you don’t have any security file scanner enabled – install the latest Prime Mover plugin. If you are using multisite, login as network administrator and go to _Network -> Plugins -> Add New Plugin -> Upload plugin_. If you are using single-site, simply login as administrator and go to _Plugins- > Add New plugin -> Upload plugin_. Finally -proceed to upload the latest zip of Prime Mover plugin and then activate/network activate (if multisite). - Check if you still have an error or not. If still cannot be activated – please deactivate all plugins in your site (if possible) – this is to test if there are some conflicts with it. And then once all plugins are deactivated – try activating/network activating Prime Mover plugin. Check if it can be activated this way. Once activated- activate the rest of the plugins one by one until you find the problematic plugin that conflicts with Prime Mover and let us know if this is the case so we can run further tests on our end. - Otherwise – you can also try [installing the plugin via SFTP method](https://kinsta.com/knowledgebase/how-to-install-wordpress-plugins/#2-how-to-install-wordpress-plugins-via-sftp) which should work in most cases as long as your server file and folder permissions are correct. - Try installing and activating other plugins (e.g. _Classic Editor_) just to test if it works. This is to check if the issue not only affects Prime Mover plugin but other plugins as well. If it affects all new plugin installations( not only Prime Mover plugin) – then you might have a server problem. In this case – please double check your server permissions and credentials to make sure its correct. * If all of the above steps failed to activate the Prime Mover plugin only (other plugins unaffected) – we need more information about your site/server. In this case – please do the following so we can assist you further: - Login to your site admin and go to _Tools -> Site Health -> click “Info” tab_- > and then click “_Copy site info to clipboard_“. - Paste the results to a text file and then share it here as your reply (by pasting also) just in case you still are not able to activate the plugin. We will try to check your site and server configuration and see if there is something wrong it. * Thanks again and please let me know how it goes. * Plugin Author [Codexonics](https://wordpress.org/support/users/codexonics/) * (@codexonics) * [1 year, 8 months ago](https://wordpress.org/support/topic/cant-activate-plugin-php-fatal-error/#post-18023940) * This ticket is now closed due to inactivity.
