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.

Hello @egn145,

The error you encountered with the Speed Optimizer plugin seems to be due to a restriction on your hosting server. The plugin requires a function called exec(), which is probably not enabled on your server. This function is essential for some of the plugin’s features to work properly.

To address this, the first step is to reach out to your hosting provider and ask if they can enable the exec() function for your website. It’s worth noting that this function is commonly disabled for security reasons, so they might not allow it. The function itself uses wp-cli and executes this command, which is part of the HTTPS force and is changing the URLs in the database to use HTTPS:
```
            // Build the command.
            $command = sprintf(
                    "wp search-replace '%s' '%s' --all-tables",
                    $from . $site_url_without_protocol,
                    $to . $site_url_without_protocol
            );

            // Execute the command.
            exec(
                    $command,
                    $output,
                    $status
            );
```

Hi Pavel, I contacted my hosting provider, but unfortunately, they won’t allow it. They would only make a rare exception for sites running on dedicated or semi-dedicated servers but not for regular web hosting ones. Therefore, sadly, I can’t use the plugin unless you change it in the future so that it doesn’t require this security setting to be off.
