Jonathan, are you able to access moodle after this screen?
as this screen is not an error, when you setup moodle on live server, it makes difference accessing it using www and without www, and when one does that this screen appears which after 3 seconds takes you to the moodle installation.
Are you able to get into moodle after that?
as you can see there is mentioned port 8888, though if you mention non-default ports (other than 80) then you have to mention them with your localhost, as Browser looks for port 80 for web presence.
you can change/mention address in your config.php file typing same address
or you can go to your moodle file directory, open folder "lib" and find file "setuplib.php"
open that file, and go to line 795
you'll find the code written
, get_string('wwwrootmismatch', 'error', $CFG->wwwroot), 3
where its mentioned wwwroot, 3
, change that into 0 (this is time in seconds showing up the same error for, that you showed above)
rest, if you want you can change the default ports for Apache and MySQL
, but ideally you must have done it before installing moodle, as may be you'll get database
