Resolved Server Error 403

Most likely this is due to ModSecurity (Web Application Firewall) blocking some requests. Please check the error_log of the domain for further information on the 403 cases. You can resolve it by either adding the [ID ...] ruleset id to the allowlist of ModSecurity (can be done on the Web Application Firewall settings page of the domain) or you could - for testing purposes - disable WAF altogether.
