Yes, the sites are using required WP version (6.3.2), and the PHP versions of the sites ranges from 7.4 to 8.0, and it’s happening regardless. SSL is configured properly. There have been no downtime errors, the only php error in the logs regarding this issue is a core alert. “[path]/.htacces: Invalid command ‘Rewri’, perhaps misspelled or defined by a module not included in the server”
I ran the Server Config Rules and it wrote properly to the htaccess file. However, this issue occurs when the plugin writes the the htaccess file automatically. Because this issue throws a 500 server error, I have to manually go in and fix the htaccess (because I can’t log into the site if there is a 500 error). I manage over 100 WP sites with this plugin, and it’s happened to approximately 30 sites over the last week since the switch from iThemes to Solid Security Basic.
