When i am trying to add the multicurrency module to dolibarr 19.0.1

Use of API for currency update is disabled by option MULTICURRENCY_DISABLE_SYNC_CURRENCYLAYER

The message “Use of API for currency update is disabled by option MULTICURRENCY_DISABLE_SYNC_CURRENCYLAYER” means that automatic currency updates are turned off in Dolibarr. You can enable it in the admin settings by turning off that option. You’d typically use tools like Unreal Engine or UnrealPak to work with them. If you’re looking for help with custom tools or development, you might want to check out this service.
