ImpressPages - Unable to add plugin / themes - Still persistent in 4.6.6?

Question

With reference to ImpressPages - Unable to add plugin / themes ( version 4.2.7 - abt 2 years ago ) the problem still seems to be persistent ?

The relevant code from /Ip/Internal/Plugins/PluginDownloader.php is;

    $fileMd5 = md5_file($archivePath);
    $rsa = new \Crypt_RSA();
    $rsa->loadKey($this->publicKey);
    $rsa->setSignatureMode(CRYPT_RSA_SIGNATURE_PKCS1);
    $verified = $rsa->verify($fileMd5, base64_decode($signature));

    if (!$verified) {
        throw new \Ip\Exception('Plugin signature verification failed.');
    } 

RSA.php is available at ;

    `require_once IP_PHPSECLIB_DIR . 'Crypt/RSA.php'`

Commands md5_file, base64_decode run properly ( tested via simple test scripts ).

I tried to echo values of $rsa and $verified;

      echo'<pre>';var_dump($rsa);
      echo'<pre>';var_dump($verified);

but got "Unknown error. Please see logs."

Tried ;

    trigger_error("///////// RSA Obj  Is /////////// :- ".$rsa,    E_USER_WARNING );
    trigger_error("///////// Verified Is /////////// :- ".$verified, E_USER_WARNING );

but got the same "Unknown error. Please see logs."

As for the Logs ( hidden under Admin-> Menu -> System -> Log ), well they showed nothing.

Next, i tried https://www.impresspages.org/docs/log - ipLog() function but it doesnt say how we can use ipLog() to see values of variables such as $rsa , $verified to troubleshoot further.

So my question to any ImpressPages guru here is;

• How do we inspect the values of $rsa, $verified ?
• How to get impresspages to install plugins via the admin interface ? or is this feature broken for the past 2 years ?

An easy solution would be to try different host.
