After installing and activating the plugin on my site and attempting to log in as admin again, I couldn’t. Instead, I got a white screen with an error message and an automated email from WordPress stating that WordPress encountered an error with the Speed Optimizer plugin (the email identified it). Also, in the email, the following error details were included. I have now deactivated the plugin.
A type E_ERROR error was found in line 229 of file /var/www/vhosts/[site address]/httpdocs/wp-content/plugins/sg-cachepress/core/Ssl/Ssl.php.
