Just tried installing EE6 on two different servers (one installation on MediaTemple, one on BlueHost) and in each case I am seeing error messages when trying to save URL and Path settings. Additionally I am seeing error messages on the front end home page. Both servers have been tested with ee_wizard and are 100% compatible - I have extensive experience running EE on both hosting services for years. These are fresh installations of EE 6.0 - the errors are appearing immediately after running installation via admin.php.
Errors I am seeing after trying to save URL and Path Settings page in backend:
Warning

ee/ExpressionEngine/Controller/Settings/Settings.php, line 209
Severity: E_WARNING

Errors I am seeing on home page (with debugging enabled):

Any ideas what might be going on here?
