Hi @reneeetje 

I suggest you to run these two commands in Magento DB.

Before run these command I would recommend to take a database backup.

UPDATE flag SET flag_data = NULL WHERE flag_code = 'system_config_snapshot';
UPDATE flag SET flag_data = NULL WHERE flag_code = 'config_hash';

I hope it will help you.

Thanks
