I recently upgraded our shop to Magento 188.8.131.52 but we've had indexing issues since.
when I run the reindex command:-
php -f /var/www/shell/indexer.php reindexall
I get this error:-
PHP Fatal error: Class 'Magento_Db_Adapter_Pdo_Mysql' not found in /var/www/app/code/core/Mage/Core/Model/Resource.php on line 175
I get the exact same error for these commands:-
php -f compiler.php clear php -f compiler.php disable
we tried changing the permissions to 775 on this file (where the class id defined)
but it didn't help.
Can anyone suggest how we can resolve this?
