That's odd indeed.. to check what's actually evaluated there, temporarily place this PHP snippet somewhere in your web server's document root with any name, adjust the YourPiwigoInstallation root path and point your browser to it:

<?php
// Change root path to your Piwigo installation, note the trailing / slash is needed.
define('PHPWG_ROOT_PATH', '/YourPiwigoInstallation/');
include_once(PHPWG_ROOT_PATH.'include/config_default.inc.php');
include_once(PHPWG_ROOT_PATH.'local/config/config.inc.php');
include_once(PHPWG_ROOT_PATH.'include/common.inc.php');
include_once(PHPWG_ROOT_PATH.'include/functions.inc.php');
include_once(PHPWG_ROOT_PATH.'admin/include/functions.php');

function lf()
{
  echo "<br>";
}

// Basically what's in admin/maintenance_env.php check_upgrade, with messages adjusted:

    if (!fetchRemote(PHPWG_URL.'/download/latest_version', $result))
    {
      echo "Can not fetch."; lf();
    }
    else
    {
      print_r($result); lf();

      $versions = array('current' => PHPWG_VERSION);
      $lines = @explode("\r\n", $result);

      // if the current version is a BSF (development branch) build, we check
      // the first line, for stable versions, we check the second line
      if (preg_match('/^BSF/', $versions['current']))
      {
        $versions['latest'] = trim($lines[0]);

        // because integer are limited to 4,294,967,296 we need to split BSF
        // versions in date.time
        foreach ($versions as $key => $value)
        {
          $versions[$key] =
            preg_replace('/BSF_(\d{8})(\d{4})/', '$1.$2', $value);
        }
      }
      else
      {
        $versions['latest'] = trim($lines[1]);
      }

      if ('' == $versions['latest'])
      {
        echo "No latest."; lf();
      }
      // concatenation needed to avoid automatic transformation by release
      // script generator
      else if ('%'.'PWGVERSION'.'%' == $versions['current'])
      {
        echo "Dev sources."; lf();
      }
      else if (version_compare($versions['current'], $versions['latest']) < 0)
      {
        echo "New version available."; lf();
      }
      else
      {
        echo "Running latest."; lf();
      }

      echo "Current: ".$versions['current']; lf();
      echo "Latest: ".$versions['latest']; lf();
    }

lf();
?>

Well, did you replace YourPiwigoInstallation with the full path to your Piwigo installation, as indicated?

BTBCpiwigo certainly is not the complete absolute file path of your installation. It might be /var/www/html/BTBCpiwigo/ or whatever, but only you can know, if you don't then your hosting provider should.

This is not a question of piwigo but of the type of installation you have:

- If you host your piwigo using a subdomain, e.g. h**ps://myp*****graphy.com, then this would be the correct setting: define('PHPWG_ROOT_PATH', './'); (at least this is how it works for me)
- If you have installed it in some folder of your main domain (e.g. h**ps://www.digitogra*****hotos) then this foldername behind the domain should be used: define('PHPWG_ROOT_PATH', '/myphotos/'); .

You can also have a look into any of the .php files in the piwigo installation. They contain this definition of  PHPWG_ROOT_PATH at the very beginning. Copy & paste it into that something.php file.

Yeah right, I should had noticed you placed the file in your Piwigo directory and for that ./ is sufficient, sorry, my bad. My intention was to not fiddle with any existing installation path.

Anyway, the result confirms some discrepancy. Where you got "New version available." from the snippet, your installation says "You are running Piwigo latest version." instead. Does the same happen when clicking "Check for upgrade" in the Tools -> Maintenance -> Environment tab?

However, dumb question, are you sure you are logged in with a Piwigo account that has the Webmaster role, not just Admin? Only the webmaster role has permission to upgrade.

No idea why this would not upgrade.

However logged in this morning, went to Tools > Maintenance

Environment tab

Clicked on check for upgrade, and it gave the option to upgrade.

No Idea, nothing has changed, no new files uploaded, yet now it works!!!

Thanks to all who offered help.
