Problem: Update from 2.0 rc1 to 2.1.37 #2482

Dear sirs,

Since a few days I not able to upload pictures over the elfinder (2.0 rc1). I receive the error: "Unable to connect to backend"

The file elfinder/php//connector.php looks like this:

// run elFinder
$connector = new elFinderConnector(new elFinder($opts));
$connector->run();

So I want to update the elfinder to 2.1.37. Also there I receive this Error message: "Unable to connect to backend. Backend not found."

The file elfinder/php/connector.minimal.php looks like this:

Any help would be appreciate. Thanks a lot sir.

@sauerlu This is a problem of file location configuration on your server, so it is not a problem of elFinder. Please configure so that elfinder/php/autoload.php is loaded correctly.
