Hello @crisvalls,
I’ve tried to recreate the issue on a test WordPress website. There are translation and captcha plugins adding code on your site’s wp-admin. I installed them both on my test site, but I had no worries logging into the Dashboard.
Your theme is also adding custom CSS code to the login page, but we can not confirm if it is causing the issue without having access to the website.
You can resolve the issue by disabling the HTML minification for the admin page. You should add the following filters in the functions.php file of your active theme:
add_filter( 'sgo_html_minify_exclude_params', 'html_minify_exclude_params' );
function html_minify_exclude_params( $exclude_params ) {
// Add the query params that you want to exclude.
$exclude_params[] = wp-admin;
$exclude_params[] = reauth;
return $exclude_params;
}
add_filter( 'sgo_html_minify_exclude_urls', 'html_minify_exclude' );
function html_minify_exclude( $exclude_urls ) {
// Add the url that you want to exclude.
$exclude_urls[] = 'https://sparrou.net/wp-login.php';
return $exclude_urls;
}The filters will disable the HTML minification for requests for wp-login.php and wp-admin. If the issue persists even after that, I would advise you to submit a support request from your SiteGround account, so the Technical Support team could take a deeper look into it.
Best regards,
