I have a Craft CMS instance that I created a copy of by tarring up the folder and then dumping the mysql database and then transferring that to a different server. On the target server I restored the folder and the database. When I attempt to access the instance, I get an error in the Apache logs:
[Mon Jul 29 15:48:01.415795 2019] AH01071: Got error 'PHP message: PHP Fatal error: Uncaught Error: Call to a member function run() on integer in /var/www/html/bsf_public/craft/app/index.php:73\nStack trace:\n#0 /var/www/html/bsf_public/public/index.php(19): require_once()\n#1 {main}\n thrown in /var/www/html/bsf_public/craft/app/index.php on line 73\n'
I have spent multiple hours chasing the errors. A phpinfo() call in a file works so I know that PHP is properly configured. So I focused on line 73 of the index.php file referenced in the error message. It has these lines (in addition to others):
// Load and run Craft
// -----------------------------------------------------------------------------
$app = require 'bootstrap.php';
$app->run();
$app is returning a value of 1. bootstrap.php has these final lines of code:
$appClass = '\Craft\WebApp';
$app = new $appClass($config);
return $app;
I can't quite figure out why the bootstrap.php is returning a 1 which is why the error message occurs. I found one other instance of this being reported in a PHP app but the post had no resolution.
Maybe a Craft CMS guru can point me the right direction although I'll bet it is some kind of permissions or PHP issue. I checked the PHP files and they all have execute permissions.
