@blake A 500 error should give something in the log, but the limited control you have over your hosting environment doesn't help. Can you please try to add the following to the index.php file at the beggining: <?php
ini_set('display_errors', 1);
error_reporting(E_ALL); And try to load the webpage again?
@blake If you're using nginx, it probably is the same issue. Unfortunately as you've read in in the thread, none of us are familiar with nginx nor able to really troubleshoot this issue, sorry about that.
I did notice that attempting to go to "index.php" causes a redirect to "index.php/install/install/install/install...etc". I had read someone here github.com/friendica/friendica… mention something similar, but I'm not sure if it's relevant.
