Hello @cbdpeter
The "No such entity with cartId" error in Magento 2 when adding an item to the cart after a PHP upgrade can be caused by various issues, such as session management problems, corrupted cart data, or issues with extensions that are not compatible with the new PHP version. Here are some steps to troubleshoot and resolve this issue:
Check PHP Compatibility
Ensure that all Magento core files and third-party extensions are compatible with the new PHP version. Magento has specific PHP version requirements, and using an incompatible version can cause issues.
Clear Cache and Session
Clear the Magento cache and session data. This can resolve issues related to old cached data or session inconsistencies.
php bin/magento cache:clean
php bin/magento cache:flush
php bin/magento setup:upgrade
php bin/magento indexer:reindex
Inspect and Clean the quote Table
Check the quote and quote_item tables in the database for any inconsistencies. You can truncate these tables if you suspect that they contain corrupted data (note that this will remove all current cart data).
Make sure to back up your database before running these commands.
TRUNCATE TABLE quote;
TRUNCATE TABLE quote_item;
TRUNCATE TABLE quote_address;
TRUNCATE TABLE quote_shipping_rate;
TRUNCATE TABLE quote_payment;
Check Session Storage Configuration
Verify that the session storage configuration is set correctly. Magento supports multiple session storage options (files, database, Redis, etc.).
Check app/etc/env.php to ensure the session storage configuration is appropriate for your environment.
Magento Version Upgrade
Ensure that your Magento version is up-to-date. Newer Magento versions come with bug fixes and improvements that might resolve your issue.
Hope it helps !
