Hello/Hi/Greetings,

When I try to upgrade I'm greeted by this message.

Warning: include_once(.//include/pwgsession.class.php): Failed to open stream: No such file or directory in /usr/local/www/piwigo/include/functions_session.inc.php on line 25

Warning: include_once(): Failed opening './/include/pwgsession.class.php' for inclusion (include_path='.:/usr/local/share/pear') in /usr/local/www/piwigo/include/functions_session.inc.php on line 25

Fatal error: Uncaught Error: Class "PwgSession" not found in /usr/local/www/piwigo/include/functions_session.inc.php:32 Stack trace: #0 /usr/local/www/piwigo/include/functions.inc.php(16): include_once() #1 /usr/local/www/piwigo/include/common.inc.php(107): include('/usr/local/www/...') #2 /usr/local/www/piwigo/index.php(11): include_once('/usr/local/www/...') #3 {main} thrown in /usr/local/www/piwigo/include/functions_session.inc.php on line 32

Not sure how to fix this, any guidance welcome.
