Error: Class "Resque_Plugin" not found when running resque.php (extension)

[vinruo]

After a fresh installation of Live Helper Chat and enabling the lhcphpresque extension, running the resque.php script to start a worker results in the following error:

Error: Class "Resque_Plugin" not found in /var/www/html/lhc/lhc_web/resque.php:152

This occurs immediately when executing the command, preventing the worker from starting. The issue appears to be related to the extension.

Any help in understanding where I might be going wrong is appreciated.
