Hi guys, am an admin and not a Magento programming guy. Have a website that was running well on Debian 11. Upgraded to Debian 12 and now am facing this error;

Fatal error: Uncaught Error: Class 'Zend_Controller_Request_Http' not found in /storage/websites/agricomnew/app/code/local/Amasty/Fpc/Model/Fpc/Front.php:103 Stack trace: #0 /storage/websites/agricomnew/app/code/core/Mage/Core/Model/Cache.php(703): Amasty_Fpc_Model_Fpc_Front->__construct() #1 /storage/websites/agricomnew/app/code/core/Mage/Core/Model/Cache.php(685): Mage_Core_Model_Cache->_getProcessor('Amasty_Fpc_Mode...') #2 /storage/websites/agricomnew/app/code/core/Mage/Core/Model/App.php(351): Mage_Core_Model_Cache->processRequest() #3 /storage/websites/agricomnew/app/Mage.php(686): Mage_Core_Model_App->run(Array) #4 /storage/websites/agricomnew/index.php(86): Mage::run('', 'store') #5 {main} thrown in /storage/websites/agricomnew/app/code/local/Amasty/Fpc/Model/Fpc/Front.php on line 103

Have no clue on where to check and seeking some advice.

Thanks!
