    When I access the plugin settings, I get an error message:

    A problem was detected during the loading of the settings

    The request returned the following errors:

    • Response code:?invalid_data
    • Status code:?500
    • Server response:?<p>There has been a critical error on this website.</p>

    Checking the error log:

    Hi @yourbudweiser,

    Really Simple SSL calls the WordPress filter xmlrpc_enabled on the line causing the error. It looks like there might be a plugin incorrectly using the xmlrpc_enabled filter on your site, as _return_false is not a valid value for this filter. It should be either false, or __return_false. Really Simple SSL does not set the _return_false value, so I expect it to be coming from a different plugin. Could you try to temporarily disable other plugins and check if the issue persists?
