SKevo alfav2 I’ve deactivated all extensions. The error was in the SSO extension not being configured correctly, redirecting the login page to null since no login route was specified. Re-enabling the extension will likely bring the issue back, so I advise that you re-configure it immediately after enabling it (or leave it disabled if you don’t need that feature)
xiaoxiaobai5724 Try clearing these two contents of this extension, then clearing the HTML header and footer, CSS, and finally clearing the cache to see if it works
