https://mooreoldsignsandantiques.com is part of a multisite. The main site mane is https://www.texasvintageshopper.com All the other sites are subdomains, mooreoldsignsandantiques.com is setup as an alias in cPanel. It has been working fine then all of a sudden no one can login we get this error “Error: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.”

I have this in the wp-config.php file define(‘cookie_domain’, $_SERVER[‘HTTP_HOST’] );
I tired
define(‘ADMIN_COOKIE_PATH’, ‘/’);
define(‘COOKIE_DOMAIN’, ”);
define(‘COOKIEPATH’, ”);
define(‘SITECOOKIEPATH’, ”);
And it messed up the whole multisite login.
I add this to the child-theme functions.php file
setcookie(TEST_COOKIE, ‘WP Cookie check’, 0, COOKIEPATH, COOKIE_DOMAIN);
if ( SITECOOKIEPATH != COOKIEPATH ) setcookie(TEST_COOKIE, ‘WP Cookie check’, 0, SITECOOKIEPATH, COOKIE_DOMAIN);
It is also on CloudFlare and I emptied all of the cache with no luck.
However, I didn’t add the domain mooreoldsignsandantiques.com to CloudFlare. I’m going to check if I should add it and how to add it.
