I think your site have old J2Store supported F0F library. Install new released F0F library, it will solve this issue. check here: F0F Releases

I understand your concern.

Upon reviewing your error message, it appears that you may have followed the migration steps improperly. Specifically, you upgraded your Joomla site from version 3 to version 4 before migrating from J2Store 3 to J2Store 4 on your Joomla 3 site.

Please note the following important steps:

Before considering an upgrade from J2Store 3 to J2Store 4, you need to install the 'j2store_migration_checker' component on your Joomla 3 site. You can download and install this component from Migration Checker Component from:- ​https://github.com/J2Store4/j2store_migration_checker/releases​.

After completing the installation of the 'j2store_migration_checker' component, go to 'Components' and select 'J2Migration Checker.' Inside the J2Migration Checker, you will find a list of unsupported plugins and modules. It's essential to unpublish all plugins and modules listed as unsupported. Once the statuses of all plugins and modules change to 'Ready to Go,' you will be ready to proceed with the upgrade from J2Store 3 to J2Store 4.

For your better understanding, please check and follow the migration steps using this migration documentation: Migration Steps Documentation:- ​https://docs.j2store.org/migration-from-j2store-3-to-4

Following these steps diligently will ensure a smooth upgrade process. Please keep in mind that after completing the migration from J2Store 3 to J2Store 4, you can then proceed with the Joomla upgrade from Joomla 3 to Joomla 4. It's crucial not to upgrade your Joomla version before completing the J2Store migration, as doing so may lead to errors.

@pklinke We would like to inform you that our J2Store version 3.x.x is only compatible with Joomla 3. The issue you are experiencing may be a result of upgrading your Joomla site from version 3 to version 4 before migrating from J2Store 3 to J2Store 4 on your Joomla 3.

If you wish to remove J2Store manually from your site, go to your Joomla administration panel, navigate to 'System' > 'Extensions' > 'Manage' and check if there are any J2Store-related extensions listed. If found, try uninstalling them from this location.

Alternatively, if you prefer to upgrade your J2Store, you can directly install our J2Store 4.x.x version on your Joomla 4 site.

Since I didn't get any help here, I "hard" uninstalled J2Store last year.

The tips after 1/2 year wouldn't have been helpful at all. So I know not to use J2Store under any circumstances.

@pklinke We want to emphasize that our J2Store version 3.x.x is specifically designed for Joomla 3 and may not be compatible with Joomla 4.x.x. It's possible that the issue you're encountering stems from upgrading your Joomla site from version 3 to version 4 before migrating from J2Store 3 to J2Store 4 on your Joomla 3 platform.
