FYI, I encounter the following on
PHP Warning: require_once(phar:///home/…/extiverse/bootstrap/app.php): failed to open stream: phar error: "bootstrap/app.php" is not a file in phar "/home/…/extiverse" in phar:///home/…/extiverse/extiverse on line 19
PHP Fatal error: require_once(): Failed opening required 'phar:///home/…/extiverse/bootstrap/app.php' (include_path='.:') in phar:///home/…/extiverse/extiverse on line 19
Currently installed in home directory, but encountered the same when installed in Flarum root.
