I host my own sites on an Ubuntu 16.04 server. I have 3 websites with the latest version of Mautic running on each. All worked until I needed to change the IP address on the server. Now 2 of the Mautic installs still work but the third has an issue. When I enter Configuration and then click either apply or Save and exit, I get Please Wait… Nothing happens until I click the back button on the browser. Changes are not saved. On the working Mautics, when I exit and save a box appears at the bottom of the browser that displays “waiting for [www.xxxxxx.com](http://www.xxxxxx.com)” On the non-working Mautic, that box does not appear. Any idea how to fix this? Thanks ---
