Hello,
I have moved your post to the General discussion as it is not related to any coin adapter.
The plugin instructs you to run these commands in your SQL console. This will change the storage engine used by your DB to store the plugin’s data to an engine that is more compatible with the plugin. You must do this for security, especially since you are using the Exchange extension.
To enter commands into your SQL console, you can use phpMyAdmin. Simply follow any guide on how to do this, such as:
How to Run a Script with phpMyAdmin in SQL for HTML5and CSS3 Programming
Enter the commands exactly as you see them (copy & paste).
If you’ve done it successfully, you will not see the warning again.
Please let me know if you face any difficulties.
with regards
